From Abu Darda (radhiAllahu ‘anhu), when death was approaching him he said:

“Shall I narrate a hadeeth to you which I heard from the Messenger of Allaah (ﷺ)? I heard the Messenger of Allaah (ﷺ) saying: ‘Worship Allaah as if you see Him, if you do not see Him, then know that He sees you. Count yourself amongst the dead, be careful of the supplication of the oppressed since it is indeed answered. Whoever from amongst you can attend the two prayers, Isha and Fajr prayer even if you have to crawl, then you should do so.’”
