مسند أحمد

Al-`Awwam narrated: an old man who was guarding the coast told me: I met Abu Salih, the freed slave of `Umar bin al-Khattab (رضي الله عنه) and he said, `Umar bin al-Khattab (رضي الله عنه) told us that the Messenger of Allah (ﷺ) said: “There is no night in which the sea does not approach the land three times and ask Allah for permission to flood it, but Allah, may He be glorified and exalted, restrains it.`
