Narrated Rab'iah b. Ka'b al-Aslami:I used to live with the Messenger of Allah (ﷺ) at night. I would bring water for his ablution and his need. He asked: Ask me. I said: Your company in Paradise. He said: Is there anything other than that ? I said: It is only that. He said: Help me for yourself by making prostrations abundantly
