پورا دن گزر گیا اور شام ہونے والی ہے۔ دریائی پانی کے بہاو پر شفق کے عکس کی چادر تن گئی ہے۔ بوڑھا ماہی گیر، جس کے ماتھے کی شکنیں مزید گہری اور ایک دوسرے کو کاٹنے لگ گئیں۔وہ تھکن کے احساس سے بڑبڑانے لگا۔"آج کا دن ہی کچھ منحوس تھا۔کوئی بڑی مچھلی ہاتھ نہ آئی"۔ بوڑھے ماہی گیر کا معاون، اٹھارہ برس کا کھلنڈرا جوان ہے۔جسےاس کی بوڑھی بیوہ ماں نے، مچھلیاں پکڑنے کے گر سیکھنے کےلیے اس کے پاس چھوڑ رکھا تھا۔یہ انتہائی جذباتی، متجسس اور ہر وقت اپنی ذات کے اندر بے تکے سوالوں کی ٹر ٹر لگائے رکھتا تھا۔ وہ ہر لمحہ کچھ نہ کچھ سوچتا ہی رہتا،خود ہی سوال اٹھاتا اور خود کو ہی جواب دے کر مطمن کر دیتا۔ لیکن پچھلے کچھ عرصے سے خدا کا منطقہ اس کے ذہن میں یوں اٹک گیا جیسے گلے میں ہڈی پھنس جاتی ہے۔سارا دن یہ سوال مسلسل پوچھ پوچھ کر اس نے اپنے استاد کا سر کھا لیا۔استاد اسے بےوقوف لڑکا سمجھتے ہوئے کئی طرح سے ٹالتا رہا۔ لڑکے نے آخری بار پوچھنے کا فیصلہ کرتے ہوئے ذرا تیکھے پن سے کہا:
"استاد! اب بتاو ہی دو، یہ خدا کس بلا کا نام ہے؟"
استاد نے جال سمیٹے اور تیوری چڑھاتے ہوئے، اسے دیکھا اور بولا۔"بکو مت، یہ کیا بکواس کر رہے ہو سنو ۔ خدا نظر نہیں آتا، لیکن رحم و کرم سے بھرپور اور انسان سے محبت کرتا ہے۔" لڑکے کے ذہن میں اٹکا یہ معاملہ جیسے سلجھ گیا ہو۔ وہ پہلے زیر لب مسکرایا، پھر ہنسا، پھر قہقہے لگانے شروع کر دیے اور رواں گہرے پانی میں چھلانگ لگا دی۔ شاید اس نے یہ سوچا ہو گا کہ مجھے بھی نظر نہیں آ...
Quran is the absolute and error free source of knowledge for all mankind. The words and meanings of the Quran both have been revealed by Allah and will remain unchanged for ever. The holy Quran was explained by the Holy prophet and by sahaba as well. Later on different scholars of Islam have made notable contribution in this regard. Many companions of the Holy prophet are famous in the explanation of the Holy Quran. Although Syyeda Aeshah is famous in the field of Hadith but she is one of most prominent Mufassrah of the Quran too. She has deep and correct knowledge of the Holy Quran. In this Article the status of Sayyedah Aesha in the field of tafseer has been discussed. Hopefully the readers will get useful information from this Article
In this thesis, we investigate gravitational collapse in f(R, T) modified theory of gravity. We focus on the study of gravitational collapse of spherically symmetric and FriedmannRobertsonWalker(FRW) metrics for both dust and perfect fluid cases. We also explore the gravitational collapse of 5D spherically symmetric spacetime in f(R, T) gravity and extend this work to N-dimensional spherically symmetric spacetimes. Furthermore, we explore the effect of electromagnetic fields on the gravitational collapse in f(R, T) modified theory of gravity. Firstly, we discuss the gravitational collapse of spherically symmetric spacetime for both dust and perfect fluid cases in f(R, T) gravity. For this purpose, we consider the spherically symmetric spacetime as the interior region and Schwarzschild metric as the exterior region. The junction conditions between the exterior and interior regions are found by matching the exterior and interior regions. The field equations are solved by taking the assumptions that the Ricci scalar as well as the trace of energy-momentum tensor are constant, for a particular f(R, T) = R + 2f(T) model. We calculate the gravitational mass of the collapsing system. Also, we discuss the apparent horizons and their time formation for different possible cases. It is shown that the term f(R0, T0) behaves as a source of repulsive force and consequently it slows the collapse of matter. We then discuss gravitational collapse in the context of f(R, T) gravity by taking FRW metric in the interior and schwarzschild background in the exterior regions of the star. We solve the field equations by taking the assumption of constant curvature and constant trace of energy-momentum tensor. We found that the terms 2λρ0−f(R0, T0) and f(R0, T0)+2λ(p0−ρ0) behave as cosmological constant for both dust and perfect fluid cases. Next, we discuss spherically symmetric perfect fluid collapse in the frame work of f(R, T ) modified theories of gravity using a five dimensional background. For this reason we consider the five dimensional spherically symmetric metric as the interior region and a five dimensional Schwarzschild metric as an exterior region. The junction conditions between the exterior and interior regions are discussed. By taking above mentioned model, the corresponding field equations are evaluated for both marginally bound L(r) = 1 and non-marginally bound L(r) 6= 1 cases. We find the apparent horizons and their time formation for different possible cases. It has been concluded that the term involving λ plays double role: it speeds up the collapse in region where ρ0 < 4p0; and it slows down the collapsing of matter when ρ0 > 4p0. Furthermore, we extend this work to the N-dimensional case and find that the collapse process becomes faster in the region ρ0 < (n + 1)p0 and slower in the region ρ0 > (n + 1)p0. Furthermore, it is noted that our results reduce to previously published results [80] found in GR for λ = 0. Finally, we analyze the effect of electromagnetic field on the gravitational collapse in f(R, T ) modified theories of gravity by taking spherically symmetric metric in the interior region and Reissner-Nordstrom ¨ metric in the exterior region. We discuss the issue of apparent horizons. We conclude that the end state of a star, in the presence of electromagnetic fields in the f(R, T ) gravity framework, is a black hole. It is shown that the collapse is slower in the region ρc < 3pc and faster in the region ρc > 3pc. Moreover, for λ = 0, our results correspond to those of GR found previously[120].
