mankind was on one religion so allah sent prophets giving glad tidings and warnings – and with them sent down the true book to judge between mankind on their differences and only those to whom it was given created disputes regarding the book after clear commands had come to them due to hostility of one another so allah by his command made the truth clear to the believers concerning their disputes and allah may guide whomever he wills to the straight path.
كان الناس أمة واحدة فبعث الله النبيين مبشرين ومنذرين وأنزل معهم الكتاب بالحق ليحكم بين الناس فيما اختلفوا فيه وما اختلف فيه إلا الذين أوتوه من بعد ما جاءتهم البينات بغيا بينهم فهدى الله الذين آمنوا لما اختلفوا فيه من الحق بإذنه والله يهدي من يشاء إلى صراط مستقيم
