In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Allaah [The Exalted] said:
هُوَ ٱلَّذِىٓ أَنزَلَ مِنَ ٱلسَّمَآءِ مَآءً۬ۖ لَّكُم مِّنۡهُ شَرَابٌ۬ وَمِنۡهُ شَجَرٌ۬ فِيهِ تُسِيمُونَ
يُنۢبِتُ لَكُم بِهِ ٱلزَّرۡعَ وَٱلزَّيۡتُونَ وَٱلنَّخِيلَ وَٱلۡأَعۡنَـٰبَ وَمِن ڪُلِّ ٱلثَّمَرَٲتِۗ إِنَّ فِى ذَٲلِكَ لَأَيَةً۬ لِّقَوۡمٍ۬ يَتَفَڪَّرُونَ
[He it is Who sends down water (rain) from the sky; from it you drink and from it (grows) the vegetation on which you send your cattle to pasture; with it He causes to grow for you the crops, the olives, the date-palms, the grapes, and every kind of fruit. Verily! In this is indeed an evident proof and a manifest sign for people who give thought. (Aayah 10-11)]. Meaning, thus one contemplates on Allaah’s Perfect Power, The One Who sends down this water from the tender and mild clouds – and His Perfect Mercy, for He placed abundant water in the clouds and they [i.e. the people] drink from it, provide drinking water for their flocks and use for their vegetation, which produces abundant fruits and numerous blessings.
وَسَخَّرَ لَڪُمُ ٱلَّيۡلَ وَٱلنَّهَارَ وَٱلشَّمۡسَ وَٱلۡقَمَرَۖ وَٱلنُّجُومُ مُسَخَّرَٲتُۢ بِأَمۡرِهِۦۤۗ إِنَّ فِى ذَٲلِكَ لَأَيَـٰتٍ۬ لِّقَوۡمٍ۬ يَعۡقِلُونَ
[And He has subjected to you the night and the day, the sun and the moon; and the stars are subjected by His Command. Surely, in this are proofs for people who understand (Aayah 12)] – Meaning, Allaah subjugated these things to you for your benefit and the various affairs related to your well-being, to such an extent that you can never do without them. At night you find repose, take rest and sleep, and during the day you disperse in pursuit of your livelihoods, the beneficial affairs related to your religion and worldly life.
And from the sun there is Diyaa [i.e. light together with heat], the moon has Noor [i.e. light without heat] and they both have brightness, which is beneficial to trees, vegetation and plants; a means of dehumidification [by way of the sun] and removal of cold weather that is harmful to the earth and bodies, and [providing] other necessities and needs due to their presence. And there is beautification of the heavens by way of the sun, the moon and the stars, a means of guiding [the people during travel] in the darkness on land and at sea, a means of knowing the time periods of the day and night, and figuring out the different months and years, and that which is related to their various sings and functions. This is why Allaah pointed out all of that in His statement: [إِنَّ فِى ذَٲلِكَ لَأَيَـٰتٍ۬ لِّقَوۡمٍ۬ يَعۡقِلُونَ – Surely, in this are proofs for people who understand] – Meaning, those who possess intellects that are utilised to reflect and ponder based on the reason behind which they were facilitated with intellects- to understand what they see and hear; and not like the observation of the heedless ones, whose observation is similar to that animals whose intellect [is not guided by divine revelation to distinguish between right and wrong].
وَمَا ذَرَأَ لَڪُمۡ فِى ٱلۡأَرۡضِ مُخۡتَلِفًا أَلۡوَٲنُهُ ۥۤۗ إِنَّ فِى ذَٲلِكَ لَأَيَةً۬ لِّقَوۡمٍ۬ يَذَّڪَّرُونَ
[And whatsoever He has created for you on this earth of varying colours and qualities from vegetation and fruits, etc. (botanical life) and from animal (zoological life). Verily! In this is a sign for people who remember. (Aayah 13)] – Meaning, whatever Allaah has created for His slaves and spread out on the face of the earth, such as animals, trees, plants and other than that- whose colours and types vary – is a sign regarding Allaah’s Perfect Power, vast kindness and Generosity, and that indeed He is the only One who has the right to be worshipped. [Ref 1]
[إِنَّ فِى ذَٲلِكَ لَأَيَةً۬ لِّقَوۡمٍ۬ يَذَّڪَّرُونَ – Verily! In this is a sign for people who remember]– Meaning, remember the favours of Allaah and His blessings, and then show gratitude. [Ref 2]
