Narrated Amir: Ali, Fadl and Usamah ibn Zayd washed the Messenger of Allah ﷺ and they put him in his grave. Marhab or Ibn AbuMarhab told me that they also made AbdurRahman ibn Awf join them. When Ali became free, he said: The People of the man serve him.
The hadith also speaks to the importance of humility and selflessness when serving others. Ali was willing to take on this task without any expectation or reward from anyone else; he simply wanted to do what was right and honourable for someone he respected deeply. This teaches us that when helping others, we should not expect anything in return but rather focus on doing what is right out of love and kindness towards our fellow human beings.
