Musa bin Salamah (may Allah have mercy on him) relates: I said to Sayyiduna Ibn Abbas (may Allah be pleased with them both): "We were with you, then we went out (on a journey) and came back, and we prayed two rak'ahs?" He said: "That is the Sunnah of Abu al-Qasim (peace and blessings be upon him), even if your noses are rubbed in the dust (that is, whether you like it or not)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ayyub (may Allah have mercy on him) except al-Harith bin Umayr (may Allah have mercy on him) and Muhammad bin Abd al-Rahman al-Tufawi (may Allah have mercy on him)."
