Narrated 'Ali bin Abi Talib:
"We departed with the Messenger of Allah (ﷺ) until he was at Harrah As-Suqya which belonged to Sa'd bin Abi Waqqas. So the Messenger of Allah (ﷺ) said: 'Bring me water for Wudu.' So he performed Wudu, then he faced the Qiblah and said: 'O Allah! Indeed Ibrahim was Your servant and Your Khalil, and he supplicated for blessings for the people of Makkah. And I am Your servant and Messenger, and I supplicate for the people of Al-Madinah; that You bless them in their Mudd and their Sa' like You blessed the people of Makkah, for each blessing let there be two blessings."
