وحَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ بِشْرٍ ، حَدَّثَنَا بَهْزُ بْنُ أَسَدٍ ، حَدَّثَنَا شُعْبَةُ ، حَدَّثَنَا ابْنُ عُثْمَانَ بْنِ عَبْدِ اللَّهِ بْنِ مَوْهَبٍ ، وَأَبُوهُ عُثْمَانُ بْنُ عَبْدِ اللَّهِ ، أَنَّهُمَا سَمِعَا مُوسَى بْنَ طَلْحَةَ ، عَنْ أَبِي أَيُّوبَ الْأَنْصَارِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ : يَا رَسُولَ اللَّهِ أَخْبِرْنِي بِعَمَلٍ يُدْخِلُنِي الْجَنَّةَ ، فَقَالَ الْقَوْمُ : مَا لَهُ مَا لَهُ ، فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : أَرَبٌ مَا لَهُ ، فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " تَعْبُدُ اللَّهَ لَا تُشْرِكُ بِهِ شَيْئًا ، وَتُقِيمُ الصَّلَاةَ ، وَتُؤْتِي الزَّكَاةَ ، وَتَصِلُ الرَّحِمَ " ذَرْهَا قَالَ : كَأَنَّهُ كَانَ عَلَى رَاحِلَتِهِ .
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 said, "He has something to ask (what he needs greatly)." The Prophet 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."
