30:48
ٱللَّهُ ٱلَّذِى يُرْسِلُ ٱلرِّيَـٰحَ فَتُثِيرُ سَحَابًا فَيَبْسُطُهُۥ فِى ٱلسَّمَآءِ كَيْفَ يَشَآءُ وَيَجْعَلُهُۥ كِسَفًا فَتَرَى ٱلْوَدْقَ يَخْرُجُ مِنْ خِلَـٰلِهِۦ ۖ فَإِذَآ أَصَابَ بِهِۦ مَن يَشَآءُ مِنْ عِبَادِهِۦٓ إِذَا هُمْ يَسْتَبْشِرُونَ
It is Allah who sends the winds, and they stir the clouds and spread them in the sky however He wills, and He makes them fragments so you see the rain emerge from within them. And when He causes it to fall upon whom He wills of His servants, immediately they rejoice

وَمِنْ ءَايَـٰتِهِۦٓ أَن يُرْسِلَ ٱلرِّيَاحَ مُبَشِّرَٰتٍ وَلِيُذِيقَكُم مِّن رَّحْمَتِهِۦ وَلِتَجْرِىَ ٱلْفُلْكُ بِأَمْرِهِۦ وَلِتَبْتَغُوا۟ مِن فَضْلِهِۦ وَلَعَلَّكُمْ تَشْكُرُونَ
And of His signs is that He sends the winds as bringers of good tidings and to let you taste His mercy and so the ships may sail at His command and so you may seek of His bounty, and perhaps you will be grateful.
وَلَقَدْ أَرْسَلْنَا مِن قَبْلِكَ رُسُلًا إِلَىٰ قَوْمِهِمْ فَجَآءُوهُم بِٱلْبَيِّنَـٰتِ فَٱنتَقَمْنَا مِنَ ٱلَّذِينَ أَجْرَمُوا۟ ۖ وَكَانَ حَقًّا عَلَيْنَا نَصْرُ ٱلْمُؤْمِنِينَ
And We have already sent messengers before you to their peoples, and they came to them with clear evidences; then We took retribution from those who committed crimes, and incumbent upon Us was support of the believers.
وَإِن كَانُوا۟ مِن قَبْلِ أَن يُنَزَّلَ عَلَيْهِم مِّن قَبْلِهِۦ لَمُبْلِسِينَ
Although they were, before it was sent down upon them - before that, in despair.
فَٱنظُرْ إِلَىٰٓ ءَاثَـٰرِ رَحْمَتِ ٱللَّهِ كَيْفَ يُحْىِ ٱلْأَرْضَ بَعْدَ مَوْتِهَآ ۚ إِنَّ ذَٰلِكَ لَمُحْىِ ٱلْمَوْتَىٰ ۖ وَهُوَ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ
So observe the effects of the mercy of Allah - how He gives life to the earth after its lifelessness. Indeed, that [same one] will give life to the dead, and He is over all things competent.
