It is narrated from Hasan. He says that Hazrat Sa’d bin ‘Ubadah submitted: O Messenger of Allah (peace and blessings be upon him)! Command me regarding charity. The Prophet (peace and blessings be upon him) said:“Give water to drink.”The narrator says: So he had two water skins set up. They were still set up, and in my childhood, I used to run between the two.
