Having witnesses: two men or more

Sayyiduna Abu Ubaydah bin al-Jarrah (may Allah be pleased with him) wrote to the people of Dayr Tayaya: I have granted safety to your lives, your properties and your places of worship, that they shall not be destroyed or broken, as long as you do not commit an offence or give shelter to a killer. If you commit an offence or give shelter to a killer, then I am free of the covenant of protection towards you. It is obligatory upon you to host a guest for three days. Indeed, we are free of responsibility for any error or lapse of the army. Sayyiduna Khalid bin al-Walid, Sayyiduna Yazid bin Abi Sufyan, Sayyiduna Shurahbil bin Hasanah and Qada'i bin Amir (may Allah be pleased with them) bore witness (became witnesses), and it was written down.

Sayyiduna Umar (may Allah be pleased with him) passed by a man who was sitting among the people writing, and he was taking more than two witnesses. He (may Allah be pleased with him) forbade him. Then, some time later, he passed by again (and he was still doing the same thing). He (may Allah be pleased with him) said: Did I not forbid you? The man said: I obeyed Allah and disobeyed you.

And in the charity deed of Sayyiduna Umar (may Allah be pleased with him) it was written: Sayyiduna Abdullah bin al-Arqam and Sayyiduna Mu'ayqib (may Allah be pleased with them both) bore witness.

And in the charity deed of Sayyiduna Ali (may Allah be pleased with him) it was written: So-and-so and so-and-so bore witness, and he wrote it.

Musa bin Salim (may Allah have mercy on him) said: When al-Hajjaj banished the people of the land, a woman came to me with a document, claiming that her father was the one who had been freed. (She said:) This is what Sayyiduna Talhah bin Ubaydullah (may Allah be pleased with him) purchased from so-and-so son of so-and-so. He bought from him his slave Dinar or Dirham for 500 dirhams of good, fine and excellent quality. He has paid him the price and has freed him for the sake of Allah, so no one has any claim over him except the claim of wala'. Witnessed by Sayyiduna al-Zubayr bin al-Awwam (may Allah be pleased with him), Abdullah bin Amir and Ziyad.
