Sunan an-Nasai
أَخْبَرَنَا قُتَيْبَةُ، أَنْبَأَنَا حَمَّادٌ، عَنْ مُحَمَّدٍ، عَنْ أَبِيهِ، عَنْ عِمْرَانَ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم " لاَ نَذْرَ فِي غَضَبٍ وَكَفَّارَتُهُ كَفَّارَةُ الْيَمِينِ " . وَقِيلَ إِنَّ الزُّبَيْرَ لَمْ يَسْمَعْ هَذَا الْحَدِيثَ مِنْ عِمْرَانَ بْنِ حُصَيْنٍ .
It was narrated that 'Imran said: The Messenger of Allah said: "There is no vow at a moment of anger and its expiation is the expiation for an oath." It was said: "Az-Zubair did not hear this Hadith from 'Imran bin Husain."
