Sahih Muslim , Book 4, Hadith 1756 (USC-MSA) ⓘ

'Uqba b. 'Amir reported: When we were in Suffa, the Messenger of Allah came out and said: Which of you would like to go out every morning to Buthan or al-'Aqiq and bring two large she-camels without being guilty of sin or without severing the ties of kinship? We said: Messenger of Allah, we would like to do it. Upon this he said: Does not one of you go out in the morning to the mosque and teach or recite two verses from the Book of Allah. the Majestic and Glorious? That is better for him than two she-camels, and three verses are better (than three she-camels). and four verses are better for him than four (she-camels), and to on their number in camels.

وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا الْفَضْلُ بْنُ دُكَيْنٍ، عَنْ مُوسَى بْنِ عُلَىٍّ، قَالَ سَمِعْتُ أَبِي يُحَدِّثُ، عَنْ عُقْبَةَ بْنِ عَامِرٍ، قَالَ خَرَجَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَنَحْنُ فِي الصُّفَّةِ فَقَالَ ‏"‏ أَيُّكُمْ يُحِبُّ أَنْ يَغْدُوَ كُلَّ يَوْمٍ إِلَى بُطْحَانَ أَوْ إِلَى الْعَقِيقِ فَيَأْتِيَ مِنْهُ بِنَاقَتَيْنِ كَوْمَاوَيْنِ فِي غَيْرِ إِثْمٍ وَلاَ قَطْعِ رَحِمٍ ‏"‏ ‏.‏ فَقُلْنَا يَا رَسُولَ اللَّهِ نُحِبُّ ذَلِكَ ‏.‏ قَالَ ‏"‏ أَفَلاَ يَغْدُو أَحَدُكُمْ إِلَى الْمَسْجِدِ فَيَعْلَمَ أَوْ يَقْرَأَ آيَتَيْنِ مِنْ كِتَابِ اللَّهِ عَزَّ وَجَلَّ خَيْرٌ لَهُ مِنْ نَاقَتَيْنِ وَثَلاَثٌ خَيْرٌ لَهُ مِنْ ثَلاَثٍ وَأَرْبَعٌ خَيْرٌ لَهُ مِنْ أَرْبَعٍ وَمِنْ أَعْدَادِهِنَّ مِنَ الإِبِلِ ‏"‏ ‏.‏
