Luqman
إِنَّ ٱللَّهَ عِندَهُۥ عِلْمُ ٱلسَّاعَةِ وَيُنَزِّلُ ٱلْغَيْثَ وَيَعْلَمُ مَا فِى ٱلْأَرْحَامِ ۖ وَمَا تَدْرِى نَفْسٌ مَّاذَا تَكْسِبُ غَدًا ۖ وَمَا تَدْرِى نَفْسٌۢ بِأَىِّ أَرْضٍ تَمُوتُ ۚ إِنَّ ٱللَّهَ عَلِيمٌ خَبِيرٌۢ
Indeed, Allah [alone] has knowledge of the Hour and sends down the rain and knows what is in the wombs. And no soul perceives what it will earn tomorrow, and no soul perceives in what land it will die. Indeed, Allah is Knowing and Acquainted.

وَإِذَا غَشِيَهُم مَّوْجٌ كَٱلظُّلَلِ دَعَوُا۟ ٱللَّهَ مُخْلِصِينَ لَهُ ٱلدِّينَ فَلَمَّا نَجَّىٰهُمْ إِلَى ٱلْبَرِّ فَمِنْهُم مُّقْتَصِدٌ ۚ وَمَا يَجْحَدُ بِـَٔايَـٰتِنَآ إِلَّا كُلُّ خَتَّارٍ كَفُورٍ
And when waves come over them like canopies, they supplicate Allah, sincere to Him in religion. But when He delivers them to the land, there are [some] of them who are moderate [in faith]. And none rejects Our signs except everyone treacherous and ungrateful.
يَـٰٓأَيُّهَا ٱلنَّاسُ ٱتَّقُوا۟ رَبَّكُمْ وَٱخْشَوْا۟ يَوْمًا لَّا يَجْزِى وَالِدٌ عَن وَلَدِهِۦ وَلَا مَوْلُودٌ هُوَ جَازٍ عَن وَالِدِهِۦ شَيْـًٔا ۚ إِنَّ وَعْدَ ٱللَّهِ حَقٌّ ۖ فَلَا تَغُرَّنَّكُمُ ٱلْحَيَوٰةُ ٱلدُّنْيَا وَلَا يَغُرَّنَّكُم بِٱللَّهِ ٱلْغَرُورُ
O mankind, fear your Lord and fear a Day when no father will avail his son, nor will a son avail his father at all. Indeed, the promise of Allah is truth, so let not the worldly life delude you and be not deceived about Allah by the Deceiver.
