Narrated Zaid bin Arqam:When `Abdullah bin Ubai said, "Do not spend on those who are with Allah's Messenger (ﷺ)," and also said, "If we return to Medina," I informed the Prophet (ﷺ) of his saying. The Ansar blamed me for that, and `Abdullah bin Ubai swore that he did not say. I returned to my house and slept. Allah's Messenger (ﷺ) then called me and I went to him. He said, "Allah has confirmed your statement." The Verse: "They are the one who say: Spend nothing......(63.7) was revealed.
حَدَّثَنَا آدَمُ، حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، قَالَ سَمِعْتُ مُحَمَّدَ بْنَ كَعْبٍ الْقُرَظِيَّ، قَالَ سَمِعْتُ زَيْدَ بْنَ أَرْقَمَ ـ رضى الله عنه ـ قَالَ لَمَّا قَالَ عَبْدُ اللَّهِ بْنُ أُبَىٍّ لاَ تُنْفِقُوا عَلَى مَنْ عِنْدَ رَسُولِ اللَّهِ. وَقَالَ أَيْضًا لَئِنْ رَجَعْنَا إِلَى الْمَدِينَةِ. أَخْبَرْتُ بِهِ النَّبِيَّ صلى الله عليه وسلم فَلاَمَنِي الأَنْصَارُ، وَحَلَفَ عَبْدُ اللَّهِ بْنُ أُبَىٍّ مَا قَالَ ذَلِكَ، فَرَجَعْتُ إِلَى الْمَنْزِلِ فَنِمْتُ فَدَعَانِي رَسُولُ اللَّهِ صلى الله عليه وسلم فَأَتَيْتُهُ فَقَالَ " إِنَّ اللَّهَ قَدْ صَدَّقَكَ ". وَنَزَلَ {هُمُ الَّذِينَ يَقُولُونَ لاَ تُنْفِقُوا} الآيَةَ. وَقَالَ ابْنُ أَبِي زَائِدَةَ عَنِ الأَعْمَشِ عَنْ عَمْرٍو عَنِ ابْنِ أَبِي لَيْلَى عَنْ زَيْدٍ عَنِ النَّبِيِّ صلى الله عليه وسلم.
