Say to them O Muhammad: "Shall I choose a judge besides Allah when it is He Who makes and gives the law whereas all other judges only interpret it? It is He Who has sent down -the Quran- distinctly expressing all that is meant leaving nothing merely implied," .Ahl al-Kitab know it is Allah's sent Book in all truth. Therefore, do not let O Muhammad those who hide the truth and contend with opposing arguments influence your feelings or put you in doubt.
