We went out with the Messenger of Allah ﷺ and when we were in the Harrah, at as-Suqya (a halting place between Makkah and Madinah) which belonged to Saʿd bin Abi Waqqas, the Messenger of Allah ﷺ said: ʿBring me some water for wudoo’.” When he had done wudoo he stood up and turned to face the qiblah, then he said takbeer, then he said: O Allah, Ibrahim was Your slave and Your close friend; he prayed for blessing for the people of Makkah. I am Muhammad, Your slave and Your Messenger; I am praying to You for the people of Madinah - bless their mudd and saʿ [weights and measures] as You blessed the people of Makkah, double the blessing You bestowed upon the people of Makkah, a twofold blessing.”
