(68) باب تَأَلُّفِ قَلْبِ مَنْ يَخَافُ عَلَى إِيمَانِهِ لِضَعْفِهِ وَالنَّهْيِ عَنِ الْقَطْعِ بِالإِيمَانِ مِنْ غَيْرِ دَلِيلٍ قَاطِعٍ
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?
