Narrated Abu Aiyub Al-Ansari:
A man said, "O Allah's Apostle! Inform me of a deed which will make me enter Paradise." The people said, "What is the matter with him? What is the matter with him?" Allah's Apostle ﷺ said, "He has something to ask (what he needs greatly)." The Prophet ﷺ said (to him), (In order to enter Paradise) you should worship Allah and join none in worship with Him: You should offer prayers perfectly, give obligatory charity (Zakat), and keep good relations with your Kith and kin." He then said, "Leave it!" (The sub-narrator said, "It seems that the Prophet was riding his she camel."
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.
