Rabi'a b. Ka'b said:
حَدَّثَنَا الْحَكَمُ بْنُ مُوسَى أَبُو صَالِحٍ ، حَدَّثَنَا هِقْلُ بْنُ زِيَادٍ ، قَالَ سَمِعْتُ الأَوْزَاعِيَّ ، قَالَ حَدَّثَنِي يَحْيَى بْنُ أَبِي كَثِيرٍ ، حَدَّثَنِي أَبُو سَلَمَةَ ، حَدَّثَنِي رَبِيعَةُ بْنُ كَعْبٍ الأَسْلَمِيُّ ، قَالَ كُنْتُ أَبِيتُ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فَأَتَيْتُهُ بِوَضُوئِهِ وَحَاجَتِهِ فَقَالَ لِي " سَلْ " . فَقُلْتُ أَسْأَلُكَ مُرَافَقَتَكَ فِي الْجَنَّةِ . قَالَ " أَوَغَيْرَ ذَلِكَ " . قُلْتُ هُوَ ذَاكَ . قَالَ " فَأَعِنِّي عَلَى نَفْسِكَ بِكَثْرَةِ السُّجُودِ " .
I was with Allah's Messenger (ﷺ) one night. and I brought him water and what he required. He said to me: Ask (anything you like). I said: I ask your company in Paradise. He (the Holy Prophet) said: Or anything else besides it. I said: That is all (what I require). He said: Then help me to achieve this for you by devoting yourself often to prostration.
