73 – Khalaf ibn Hisham narrated to us; Abu ʿAwanah related from Ziyad ibn ʿIlaqah, from al-Mughirah ibn Shuʿbah, who said: “The Messenger of Allah ﷺ would stand in prayer until his feet became swollen. Someone said to him, ‘O Prophet of Allah, do you subject yourself to this when your sins, past and future, have already been forgiven?’ He replied, ‘Should I not, then, be a grateful servant?’”
