ضَرَبَ ٱللَّهُ مَثَلًا رَّجُلًا فِيهِ شُرَكَآءُ مُتَشَـٰكِسُونَ وَرَجُلًا سَلَمًا لِّرَجُلٍ هَلْ يَسْتَوِيَانِ مَثَلًا ۚ ٱلْحَمْدُ لِلَّهِ ۚ بَلْ أَكْثَرُهُمْ لَا يَعْلَمُونَ
Allah presents an example: a slave owned by quarreling partners and another belonging exclusively to one man - are they equal in comparison? Praise be to Allah! But most of them do not know.

وَلَقَدْ ضَرَبْنَا لِلنَّاسِ فِى هَـٰذَا ٱلْقُرْءَانِ مِن كُلِّ مَثَلٍ لَّعَلَّهُمْ يَتَذَكَّرُونَ
And We have certainly presented for the people in this Qur'an from every [kind of] example - that they might remember.
قُرْءَانًا عَرَبِيًّا غَيْرَ ذِى عِوَجٍ لَّعَلَّهُمْ يَتَّقُونَ
[It is] an Arabic Qur'an, without any deviance that they might become righteous.
إِنَّكَ مَيِّتٌ وَإِنَّهُم مَّيِّتُونَ
Indeed, you are to die, and indeed, they are to die.
ثُمَّ إِنَّكُمْ يَوْمَ ٱلْقِيَـٰمَةِ عِندَ رَبِّكُمْ تَخْتَصِمُونَ
Then indeed you, on the Day of Resurrection, before your Lord, will dispute.
