Sahih Muslim , Book 1, Hadith 279 (USC-MSA) ⓘ
The same hadith has been narrated on the authority of Muhammad b Sa'd and these words (are also there): The Messenger of Allah gave a stroke on my neck or between my two shoulders and said: Sa'd, do you fight with me simply because I gave (a share) to a man?
وَحَدَّثَنَا الْحَسَنُ الْحُلْوَانِيُّ، حَدَّثَنَا يَعْقُوبُ، حَدَّثَنَا أَبِي، عَنْ صَالِحٍ، عَنْ إِسْمَاعِيلَ بْنِ مُحَمَّدٍ، قَالَ سَمِعْتُ مُحَمَّدَ بْنَ سَعْدٍ، يُحَدِّثُ هَذَا فَقَالَ فِي حَدِيثِهِ فَضَرَبَ رَسُولُ اللَّهِ صلى الله عليه وسلم بِيَدِهِ بَيْنَ عُنُقِي وَكَتِفِي ثُمَّ قَالَ " أَقِتَالاً أَىْ سَعْدُ إِنِّي لأُعْطِي الرَّجُلَ " .
