Haddab ibn Khalid narrated to us, Hammad ibn Salamah narrated to us, from Thabit, from Mutarrif — and I did not understand Mutarrif from Haddab — from 'Imran ibn Husayn, may Allah be pleased with them both, that the Messenger of Allah, peace and blessings be upon him, said to him or to another man: "Did you fast the last days of Sha'ban?" He said: "No." He said: "Then when you break your fast, fast two days."
