Sahih al-Bukhari 5983
Narrated Abu Aiyub Al-Ansari:
A man said, "O Allah's Messenger (ﷺ)! 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 Messenger (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 (ﷺ) was riding his she camel."
حَدَّثَنِي عَبْدُ الرَّحْمَنِ، حَدَّثَنَا بَهْزٌ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا ابْنُ عُثْمَانَ بْنِ عَبْدِ اللَّهِ بْنِ مَوْهَبٍ، وَأَبُوهُ، عُثْمَانُ بْنُ عَبْدِ اللَّهِ أَنَّهُمَا سَمِعَا مُوسَى بْنَ طَلْحَةَ، عَنْ أَبِي أَيُّوبَ الأَنْصَارِيِّ ـ رضى الله عنه أَنَّ رَجُلاً قَالَ يَا رَسُولَ اللَّهِ أَخْبِرْنِي بِعَمَلٍ يُدْخِلُنِي الْجَنَّةَ‏.‏ فَقَالَ الْقَوْمُ مَالَهُ مَالَهُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ أَرَبٌ مَالَهُ ‏"‏‏.‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ تَعْبُدُ اللَّهَ لاَ تُشْرِكُ بِهِ شَيْئًا، وَتُقِيمُ الصَّلاَةَ، وَتُؤْتِي الزَّكَاةَ، وَتَصِلُ الرَّحِمَ، ذَرْهَا ‏"‏‏.‏ قَالَ كَأَنَّهُ كَانَ عَلَى رَاحِلَتِهِ‏.‏
