ضَرَبَ اللَّهُ مَثَلً رَّجُلً فِيهِ شُرَكَاء مُتَشَاكِسُونَAllah puts forth a parable:a man belonging to many partners disputing with one another,meaning, they were disputing concerning that slave in whom they all had a share.وَرَجُلً سَلَمًا لِّرَجُلٍand a (slave) man belonging entirely to one master.means, no one owned him except that one man.هَلْ يَسْتَوِيَانِ مَثَلًAre those two equal in comparison?meaning, they are not the same.By the same token, the idolator who worships other gods besides Allah and the sincere believer who worships none besides Allah, with no partner or associate, are not equal. What comparison can there be between them?Ibn Abbas, may Allah be pleased with him, Mujahid and others said,"This Ayah is the parable of the idolator and the sincere believer."Because this parable is so clear and obvious,Allah then says:الْحَمْدُ لِلَّهِAll the praises and thanks be to Allah!i.e., for establishing proof against them.بَلْ أَكْثَرُهُمْ لَا يَعْلَمُونَBut most of them know not.means, and for this reason they associate others in worship with Allah.The fact that the Messenger of Allah and Quraysh will die, and how They will dispute before Allah Allah's saying;إِنَّكَ مَيِّتٌ وَإِنَّهُم مَّيِّتُونَ
