It is narrated from Imam Nafi' (may Allah have mercy on him) that Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said at the time of his death: "I do not grieve over anything of this world that has passed me by, except three things: fasting in the burning heat of midday, that I did not spread my feet apart in prayer (through long standing), that is, I did not lengthen the prayer, and (the third) my seeking release (iqalah, asking to withdraw) in the matter of the pledge of allegiance."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Nafi' except Muhammad bin Ishaq, and no one from Muhammad except Sinan bin Harun; Zakariyya bin Yahya Zahmawayh is alone in narrating it."
