Musnad Ahmad 936
It was narrated from `Ali bin Abi Talib (رضي الله عنه) that he said:
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 Sa`d bin Abi Waqqas, the Messenger of Allah (ﷺ) said: `Bring 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 sa` [weights and measures] as You blessed the people of Makkah, double the blessing You bestowed upon the people of Makkah, a twofold blessing.”
