عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ إِنِّي إِذَا رَأَيْتُكَ طَابَتْ نَفْسِي وَقَرَّتْ عَيْنِي فَأَنْبِئْنِي عَنْ كُلِّ شَيْءٍ فَقَالَ ((كُلُّ شَيْءٍ خُلِقَ مِنْ مَاءٍ)) قَالَ قُلْتُ يَا رَسُولَ اللَّهِ أَنْبِئْنِي عَنْ أَمْرٍ إِذَا أَخَذْتُ بِهِ دَخَلْتُ الْجَنَّةَ قَالَ ((أَفْشِ السَّلَامَ وَأَطْعِمِ الطَّعَامَ وَصِلِ الْأَرْحَامَ وَقُمْ بِاللَّيْلِ وَالنَّاسُ نِيَامٌ ثُمَّ ادْخُلِ الْجَنَّةَ بِسَلَامٍ))
It is narrated from Sayyiduna Abu Huraira (may Allah be pleased with him), he says: I said, "O Messenger of Allah! When I see you, my soul becomes happy and my eyes are cooled, so tell me about everything." The Prophet (peace and blessings be upon him) said: "Everything was created from water." I said, "O Messenger of Allah! Tell me about a command such that if I act upon it, I will enter Paradise." The Prophet (peace and blessings be upon him) said: "Spread peace, feed (others), maintain ties of kinship, and stand (in prayer) at night when people are sleeping, and you will enter Paradise in peace."
