Qur'ān 39:29 · Az-Zumar (الزمر)

ضَرَبَ ٱللَّهُ مَثَلًۭا رَّجُلًۭا فِيهِ شُرَكَآءُ مُتَشَـٰكِسُونَ وَرَجُلًۭا سَلَمًۭا 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.
