And if you are in doubt as to that which We have revealed to Our servant, then produce a chapter like it and call on your witnesses besides Allah if you are truthful.

Nay! were you witnesses when death visited Yaqoub, when he said to his sons: What will you serve after me? They said: We will serve your god and the god of your fathers, Ibrahim and Ismail and Ishaq, one Allah only, and to Him do we submit.

I did not say to them aught save what Thou didst enjoin me with: That serve Allah, my Lord and your Lord, and I was a witness of them so long as I was among them, but when Thou didst cause me to die, Thou wert the watcher over them, and Thou art witness of all things.

Therefore Allah is sufficient as a witness between us and you that we were quite unaware of your serving (us).

Say: Allah suffices as a witness between me and you; surely He is Aware of His servants, Seeing.

Say: O Allah! Originator of the heavens and the earth, Knower of the unseen and the seen! Thou (only) judgest between Thy servants as to that wherein they differ.
