42. Ash-Shura/The Consultation

42. Ash-Shura/The Consultation

I/We begin by the Blessed Name of Allah

The Immensely Merciful to all, The Infinitely Compassionate to everyone.

42:01
a. Ha. Mim.

42:02
a. `Ayn. Sin. Qaf.

42:03
a. Likewise Allah, The Almighty, The All-Wise reveals on to you – O The Prophet - as HE did
to those Prophets before you.

42:04
a. Whatever is within the celestial realm and whatever is within the terrestrial world belongs to HIM,
b. for HE is All-Exalted, All-Supreme.

42:05
a. The celestial realm above them will almost burst apart, in awe of HIM, exalted be HE,
b. while the angels glorify the Praise of their Rabb- The Lord, and
c. seek forgiveness of whoever is on the earth.
d. Indeed, Allah is The Oft-Forgiving to the one who repents, The Infinitely Compassionate
towards the one who lives repentantly.

42:06
a. And as for those who take protectors other than HIM,
b. Allah is Ever-Watchful over them, and
c. you - O The Prophet - are not a guardian over them.

42:07
a. And so WE have revealed onto you a Qur’an in Arabic -
b. so you may warn people of the Mother of all Cities – Makkah – and communities and lands
around it.
c. And warn them of the coming of the Time of Assembly, about which there is absolutely no doubt,
d. when a group of them will be in the Paradise, and a group in the Blazing Fire.

42:08
a. And if Allah had so wanted, HE could have easily made them all into one single community
of believers,
b. but HE...

رتن ہندی کے دعوی صحابیت کا تحقیقی جائزہ

Ratan Hindi was born in the Indian side of the Punjab in the 6th AH. He claimed that he had met Prophet Muḥammad (PBUH) in Madinah; had accepted Islam in his presence; joined the wedding ceremony of Fatimah (RA) and had also took part in the battle of trench (Ghazwah-e-Khandaq). He also affirmed that his long age was due to the blessings of the Prophet (PBUH) who prayed for his long life. It is also said that he had witnessed the miracle of the splitting of moon in India. The present paper, after proper investigation conducted in the light of original sources, i.e. Ḥadith and its Sciences, books of Rijal and history of Islam prove his claim of Ṣahabiyyat to be false and baseless. It also presents definition of a Ṣahabi (Prophet’s Companion) along with conditions deemed by scholars of Ḥadith for such a position.

Monitoring and Measurement of Absorbing Aerosol and its Climatic Implications in Karachi, Pakistan

This thesis is a collection of studies focusing on absorption characteristics of aerosol particles using satellite and ground data as well as model simulations at an urban environment in Karachi. First of all, identification of absorbing aerosols through various aerosol optical properties was performed. After that, a study of temporal variation of absorbing Black Carbon (BC) aerosol and their impact on meteorological parameters and surface reflectance was carried out. Finally, the radiative effect of absorbing BC aerosols was investigated. In order to seasonally characterize the absorbing aerosols into different types, the optical properties of aerosol retrieved from AErosol RObotic NETwork (AERONET) and Ozone Monitoring Instrument (OMI) were utilized. Firstly, the OMI Absorption Aerosol Optical Depth (AODabs) was validated with AERONET AODabs and was found to have a high degree of correlation. Then, based on this validation, characterization was conducted by analyzing aerosol Fine Mode Fraction (FMF), Angstrom Exponent (AE), Absorption Angstrom Exponent (AAE), Single Scattering Albedo (SSA) and Aerosol Index (AI) and their mutual correlation, to identify the absorbing aerosol types and also to examine the variability in seasonal distribution. The absorbing aerosols were characterized into Mostly Black Carbon (BC), Mostly Dust and Mixed BC & Dust. The results revealed that Mostly BC aerosols contributed dominantly during winter and postmonsoon whereas, Mostly Dust was dominant during summer and premonsoon. These types of absorbing aerosol were also confirmed with the MODerate resolution Imaging Spectroradiometer (MODIS) and Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) observations. Furthermore, BC mass concentration was measured continuously for every five-minute interval with ground-based Aethalometer at an urban site in Karachi. In this study, the temporal (diurnal, monthly and seasonal) variations of BC and its relationship with meteorological variables were analyzed. Monthly averaged concentrations of BC ranged from 2.2 to 12.5 μg/m3, with maximum in the month of January, 2007 and minimum in the month of June, 2006. BC showed higher concentrations during the months of January, February and November while lower during the months of May, June, July and August throughout the years. It also displayed comparatively high concentrations during winter and postmonsoon, while moderate during premonsoon and low during summer. Diurnal analysis of BC concentration showed sharp peaks between 07:00 and 09:00 LST and again around 22:00 during all the months. Moreover, the relationship between BC concentration and meteorological variables such as Temperature (Temp), Relative Humidity (RH), Wind Speed (WS), Wind Direction (WD), VISibility (VIS) and RainFall (RF) was found and it was observed that BC concentration showed an inverse relationship with all these meteorological variables. The results revealed that BC aerosol concentration showed significant inverse relationship with surface reflectance with correlation coefficient (R) of -0.77 which implies that rise in BC aerosol concentration strongly reduces the surface reflectance. In contrast, the lower the BC aerosol concentration, the higher the surface reflectance. In addition, a significant negative correlation was recorded during all seasons showing that increase in BC aerosol concentration was accompanied with reduction in surface reflectance. The opposite relation between BC aerosol concentration and surface reflectance is relatively higher during the premonsoon and winter followed by postmonsoon, while it is lower during summer. With observations of BC aerosol concentrations, optical and radiative properties were obtained over the urban city of Karachi during the period of March 2006-December 2008. BC concentrations were continuously measured using an Aethalometer, whereas optical and radiative properties were estimated through the Optical Properties of Aerosols and Clouds (OPAC) and Santa Barbra DISORT Atmospheric Radiative Transfer (SBDART) models, respectively. The measured BC concentrations were higher during January, February and November, while these were found to be lower during May, June, July and August throughout the duration of the study. A maximum peak value was observed during January 2007 while the minimum value was observed during June 2006. The Short Wave (SW) BC Aerosol Radiative Forcing (ARF) at Top of the Atmosphere (ToA) and within the ATMOSphere (ATMOS) were positive during all the months, whereas negative BC ARF values were found at the SurFaCe (SFC). Overall, all three RF components at SW indicated that the heating by absorption of BC aerosols is higher during January, February and November mostly due to their enhanced presence, higher BC Aerosol Optical Depth (AOD) in combination with low SSA, though the surface reflectance was low. While relatively lower values of ARF were found during May, June, July and August, these were attributed to lower BC concentrations and BC AOD coupled with higher SSA even though surface reflectance was much higher in these months as compared to other months. Conversely, the Long Wave (LW) BC ARF at ToA remained positive, and BC ARF at SFC was positive whereas, BC ARF in ATMOS shifted towards positive values (heating effect) during June-August when an increase in water vapor content was found. Finally, the net (SW + LW) BC ARF at ToA and in ATMOS were found to be positive while BC ARF at SFC were found to be negative. It should be noted that a systematic increase in Atmospheric Heating Rate (AHR) was found during October to January underlining the significant effect of absorbing BC aerosols. Moreover, we found the highest correlation between AODabs and BC ARF in ATMOS followed by correlation with SFC and then with ToA. Similar to BC ARF, the values of all the three BC Absorption Forcing Efficiency (AFE) were found to be at a minimum during June 2006 while these were maximum during January 2007. On an average, the contribution of BC to the total ARF was found to greater than 80% for the whole observational period and contribute up to 99 % during January 2007.
