كتاب الإيمان
Chapter 68: Being kind to one for whose faith there is concern because it is weak; Prohibition of attributing Faith to someone without definitive evidence
باب تَأَلُّفِ قَلْبِ مَنْ يَخَافُ عَلَى إِيمَانِهِ لِضَعْفِهِ وَالنَّهْيِ عَنِ الْقَطْعِ بِالإِيمَانِ مِنْ غَيْرِ دَلِيلٍ قَاطِعٍ
Sahih Muslim 150 d
The same hadith has been narrated on the authority of Muhammad b Sa'd and these words (are also there)
The Messenger of Allah (ﷺ) 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 " .
