مُسْنَدُ أَحْمَدَ
Musnad Ahmad 3033
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated from 'Abdullah bin ‘Abbas (رضي الله عنه) that The Messenger of Allah (ﷺ) seated him behind him on his mount, and when the mount rose up with him, the Messenger of Allah (ﷺ) said Allahu Akbar three times, and Subhan Allah three times, and he said La ilaha illallah three times. Then he leaned on him and smiled. Then he turned to me and said: "There is no man who gets on his mount and does what I have done, but Allah, may He be blessed and exalted, will turn to him and smile at him as I smiled at you."
