It was narrated from Rabī’ah Ibn Ka’b Al Aslamī that he said, “I was spending the night with Allāh’s Messenger (May Allāh praise him and Peace be upon him) and brought him water for wudhū` (ablution) and what he needed and he said to me, “Ask for what you want” so I said, “I ask you that I be with you in Paradise.” He said, “Anything else?” So, I said, “That is all.” So, he said, “Then help me by prostrating a great deal”” [Muslim: 482].
