If you have doubts about what We have sent down to Our servant, produce another sura equal to it, and call your witnesses, besides Allah, if you are telling the truth. (2:23)
And when We made a covenant with you not to shed your blood and not to expel one another from your homes, you agreed and were all witnesses. (2:84)
In this way We have made you a middlemost community, so that you may act as witnesses against mankind and the Messenger as a witness against you. We only appointed the direction you used to face in order to know those who follow the Messenger from those who turn round on their heels. Though in truth it is a very hard thing–except for those Allah has guided. Allah would never let your faith go to waste. Allah is All-Gentle, Most Merciful to mankind. (2:143)

You who believe! When you take on a debt for a specified period, write it down. A writer should write it down between you justly. No writer should refuse to write; as Allah has taught him, so he should write. The one incurring the debt should dictate and should have fear of Allah, his Lord and not reduce it in any way. If the person incurring the debt is incompetent or weak or unable to dictate, then his guardian should dictate for him justly. Two men among you should act as witnesses. But if there are not two men, then a man and two women with whom you are satisfied as witnesses; then if one of them forgets, the other can remind her. Witnesses should not refuse when they are called upon. Do not think it too trivial to write down, whether small or large, with the date that it falls due. Doing that is more just in Allah’s sight and more helpful when bearing witness and more likely to eliminate any doubt–unless it is an immediate transaction hand to hand, taken and given without delay. There is nothing wrong in your not writing that down. Call witnesses when you trade. Neither writer nor witness should be put under pressure. If you do that, it is deviancy on your part. Have fear of Allah and Allah will give you knowledge. Allah has knowledge of all things. (2:282)

I am with you as one of the witnesses.’ (3:81)
