Good Manners and Form (Al-Adab)
78/10. Chapter:
Superiority of good relations with relatives
Sahih Bukhari
حَدَّثَنَا أَبُو الْوَلِيدِ، حَدَّثَنَا شُعْبَةُ، قَالَ أَخْبَرَنِي ابْنُ عُثْمَانَ، قَالَ سَمِعْتُ مُوسَى بْنَ طَلْحَةَ، عَنْ أَبِي أَيُّوبَ، قَالَ قِيلَ يَا رَسُولَ اللَّهِ، أَخْبِرْنِي بِعَمَلٍ، يُدْخِلُنِي الْجَنَّةَ.
Narrated Abu Ayyub Al-Ansari: It was said" "O Allah's Messenger! Inform me of a deed which will make me enter Paradise." (continues through a different chain in the next hadith)
