Abu Tamim al-Jayshani (a Successor) reports: Our gathering assembled in Tripoli, and with us were Sayyiduna Hubayb al-Ghifari and Sayyiduna Amr bin al-As (may Allah be pleased with them both), both Companions of the Messenger of Allah (peace and blessings be upon him). Sayyiduna Amr (may Allah be pleased with him) said: The best way of making up Ramadan (is to fast the days consecutively). At this Sayyiduna Hubayb al-Ghifari (may Allah be pleased with him) said: "We do not make a distinction in making up Ramadan"; Allah Almighty only said: "Then (let him fast) a number of other days."
