Musannaf Ibn Abi Shaybah

Hazrat Suwaid bin Qais says that I and Makhrifah Abdi brought cloth from the place of Hajar. The Prophet ﷺ came to us and wanted to buy cloth. We had a person who weighed goods and used to weigh for wages. The Messenger of Allah, peace and blessings be upon him, said to him: Weigh and give a little extra.

Hazrat Jabir (may Allah be pleased with him) narrates that the Holy Prophet (peace and blessings be upon him) bought a camel from me, weighed out the price for me, and gave me something extra as well.

Hazrat Jabir (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) owed me some debt; he repaid that and also gave me something extra.

Hazrat Khalid narrates that Hazrat Hasan bin Ali (may Allah be pleased with him) owed me a debt. I went to him to collect it, and at that time he was coming out of the bathhouse, and the effects of henna were on his nails, and his maid was scraping off his henna with a bottle. He called for a vessel-like pouch in which there were dirhams, and said to me, "Take this." I said, "This is more than my due." He said, "Keep it." So I kept it, and in it I found sixty or seventy dirhams more than my right.

Ibrahim says that there is no harm in giving more in weight.
