Musannaf Ibn Abi Shaybah

Hazrat Muhammad bin Sirin (may Allah have mercy on him) narrates that Amr bin Harith (may Allah have mercy on him) sent a marriage proposal for the daughter of Adi bin Hatim (may Allah be pleased with him). Adi bin Hatim (may Allah be pleased with him) said that the dowry will be determined according to my decision. Amr bin Harith consulted his friends, and they said, "Will you make a man from Tayy the judge in your marriage matter?" Even then, Amr bin Harith entrusted him with the decision. So Hazrat Adi decided that the Sunnah of the Prophet (ﷺ) is four hundred and eighty. Amr sent him ten thousand and said, "Please arrange the departure of your daughter."
