2:23And if you are in doubt about what We have revealed to Our servant, then produce a chapter like these, and call your witnesses apart from God, if you are truthful.

2:84And We made a covenant with you: “You shall not shed the blood of your own, nor shall you evict your own from your homes.” You agreed, and were all witnesses.

2:133Or were you witnesses when death approached Jacob, and he said to his sons, “What will you worship after Me?” They said, “We will worship your God, and the God of your fathers, Abraham, Ishmael, and Isaac; One God; and to Him we submit.”

2:143Thus We made you a moderate community, that you may be witnesses to humanity, and that the Messenger may be a witness to you. We only established the direction of prayer, which you once followed, that We may distinguish those who follow the Messenger from those who turn on their heels. It is indeed difficult, except for those whom God has guided. But God would never let your faith go to waste. God is Kind towards the people, Merciful.

2:185Ramadan is the month in which the Quran was revealed. Guidance for humanity, and clear portents of guidance, and the Criterion. Whoever of you witnesses the month, shall fast it. But whoever is sick, or on a journey, then a number of other days. God desires ease for you, and does not desire hardship for you, that you may complete the number, and celebrate God for having guided you, so that you may be thankful.

2:204Among the people is he whose speech about the worldly life impresses you, and he calls God to witness what is in his heart, while he is the most hostile of adversaries.

2:282O you who believe! When you incur debt among yourselves for a certain period of time, write it down. And have a scribe write in your presence, in all fairness. And let no scribe refuse to write, as God has taught him. So let him write, and let the debtor dictate. And let him fear God, his Lord, and diminish nothing from it. But if the debtor is mentally deficient, or weak, or unable to dictate, then let his guardian dictate with honesty. And call to witness two men from among you. If two men are not available, then one man and two women whose testimony is acceptable to all—if one of them fails to remember, the other would remind her. Witnesses must not refuse when called upon. And do not think it too trivial to write down, whether small or large, including the time of repayment. That is more equitable with God, and stronger as evidence, and more likely to prevent doubt—except in the case of a spot transaction between you—then there is no blame on you if you do not write it down. And let there be witnesses whenever you conclude a contract, and let no harm be done to either scribe or witness. If you do that, it is corruption on your part. And fear God. God teaches you. God is aware of everything.
