I was with Messenger of Allah 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.
كُنْتُ أَبِيتُ مَعَ رَسُولِ اللَّهِ ﷺ فَأَتَيْتُهُ بِوَضُوئِهِ وَحَاجَتِهِ فَقَالَ لِي سَلْ فَقُلْتُ أَسْأَلُكَ مُرَافَقَتَكَ فِي الْجَنَّةِ قَالَ أَوَغَيْرَ ذَلِكَ قُلْتُ هُوَ ذَاكَ قَالَ فَأَعِنِّي عَلَى نَفْسِكَ بِكَثْرَةِ السُّجُودِ
