Sahih al-Bukhari, Volume 6, Book 60, Hadith 424 (USC-MSA) ⓘ

Narrated Zaid bin Arqam: I was with my uncle and I heard `Abdullah bin Ubai bin Salul, saying, "Don't spend on those who are with Allah's Messenger that they may disperse and go away from him." He also said, "If we return to Medina, surely, the more honorable will expel the meaner." So I informed my uncle of that and then my uncle informed Allah's Messenger thereof. Allah's Messenger sent for `Abdullah bin Ubai and his companions. They swore that they did not say anything of that sort Allah's Messenger deemed their statement true and rejected mine. Thereof I became as distressed as I have never been before, and stayed at home. Then Allah revealed (Surat Al-Munafiqin): 'When the hypocrites come to you.....(63.1) They are the ones who say: Spend nothing on those who are with Allah's Messenger..(63.7) Verily the more honorable will expel therefrom the meaner..' (63.7-8) Allah's Messenger sent for me and recited that Sura for me and said, "Allah has confirmed your statement." 'That is because they believed, then disbelieved, so a seal was set on their hearts, therefore they understand not.' (63.3)

حَدَّثَنَا آدَمُ بْنُ أَبِي إِيَاسٍ، حَدَّثَنَا إِسْرَائِيلُ، عَنْ أَبِي إِسْحَاقَ، عَنْ زَيْدِ بْنِ أَرْقَمَ ـ رضى الله عنه ـ قَالَ كُنْتُ مَعَ عَمِّي فَسَمِعْتُ عَبْدَ اللَّهِ بْنَ أُبَىٍّ ابْنَ سَلُولَ يَقُولُ لاَ تُنْفِقُوا عَلَى مَنْ عِنْدَ رَسُولِ اللَّهِ حَتَّى يَنْفَضُّوا‏.‏ وَقَالَ أَيْضًا لَئِنْ رَجَعْنَا إِلَى الْمَدِينَةِ لَيُخْرِجَنَّ الأَعَزُّ مِنْهَا الأَذَلَّ‏.‏ فَذَكَرْتُ ذَلِكَ لِعَمِّي فَذَكَرَ عَمِّي لِرَسُولِ اللَّهِ صلى الله عليه وسلم فَأَرْسَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِلَى عَبْدِ اللَّهِ بْنِ أُبَىٍّ وَأَصْحَابِهِ، فَحَلَفُوا مَا قَالُوا، فَصَدَّقَهُمْ رَسُولُ اللَّهِ صلى الله عليه وسلم وَكَذَّبَنِي، فَأَصَابَنِي هَمٌّ لَمْ يُصِبْنِي مِثْلُهُ، فَجَلَسْتُ فِي بَيْتِي، فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ ‏{‏إِذَا جَاءَكَ الْمُنَافِقُونَ‏}‏ إِلَى قَوْلِهِ ‏{‏هُمُ الَّذِينَ يَقُولُونَ لاَ تُنْفِقُوا عَلَى مَنْ عِنْدَ رَسُولِ اللَّهِ‏}‏ إِلَى قَوْلِهِ ‏{‏لَيُخْرِجَنَّ الأَعَزُّ مِنْهَا الأَذَلَّ‏}‏ فَأَرْسَلَ إِلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَرَأَهَا عَلَىَّ ثُمَّ قَالَ ‏"‏ إِنَّ اللَّهَ قَدْ صَدَّقَكَ ‏"‏‏.‏
