The Cattle
قُلْ أَرَءَيْتَكُمْ إِنْ أَتَىٰكُمْ عَذَابُ ٱللَّهِ أَوْ أَتَتْكُمُ ٱلسَّاعَةُ أَغَيْرَ ٱللَّهِ تَدْعُونَ إِن كُنتُمْ صَـٰدِقِينَ
Say, "Have you considered: if there came to you the punishment of Allah or there came to you the Hour - is it other than Allah you would invoke, if you should be truthful?"

وَمَا مِن دَآبَّةٍ فِى ٱلْأَرْضِ وَلَا طَـٰٓئِرٍ يَطِيرُ بِجَنَاحَيْهِ إِلَّآ أُمَمٌ أَمْثَالُكُم ۚ مَّا فَرَّطْنَا فِى ٱلْكِتَـٰبِ مِن شَىْءٍ ۚ ثُمَّ إِلَىٰ رَبِّهِمْ يُحْشَرُونَ
And there is no creature on [or within] the earth or bird that flies with its wings except [that they are] communities like you. We have not neglected in the Register a thing. Then unto their Lord they will be gathered.
وَٱلَّذِينَ كَذَّبُوا۟ بِـَٔايَـٰتِنَا صُمٌّ وَبُكْمٌ فِى ٱلظُّلُمَـٰتِ ۗ مَن يَشَإِ ٱللَّهُ يُضْلِلْهُ وَمَن يَشَأْ يَجْعَلْهُ عَلَىٰ صِرَٰطٍ مُّسْتَقِيمٍ
But those who deny Our verses are deaf and dumb within darknesses. Whomever Allah wills - He leaves astray; and whomever He wills - He puts him on a straight path.
بَلْ إِيَّاهُ تَدْعُونَ فَيَكْشِفُ مَا تَدْعُونَ إِلَيْهِ إِن شَآءَ وَتَنسَوْنَ مَا تُشْرِكُونَ
No, it is Him [alone] you would invoke, and He would remove that for which you invoked Him if He willed, and you would forget what you associate [with Him].
وَلَقَدْ أَرْسَلْنَآ إِلَىٰٓ أُمَمٍ مِّن قَبْلِكَ فَأَخَذْنَـٰهُم بِٱلْبَأْسَآءِ وَٱلضَّرَّآءِ لَعَلَّهُمْ يَتَضَرَّعُونَ
And We have already sent [messengers] to nations before you, [O Muhammad]; then We seized them with poverty and hardship that perhaps they might humble themselves [to Us].
