وَعَنْ جَابِرٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَخَذَ بِيَدِ مَجْذُومٍ فَوَضَعَهَا مَعَهُ فِي الْقَصْعَةِ وَقَالَ: «كُلْ ثِقَةً بِاللَّهِ وَتَوَكُّلًا عَلَيْهِ» . رَوَاهُ ابْن مَاجَه
Jabir told that God’s messenger took a man who was suffering from tubercular leprosy by the hand, and putting it along with his own in the dish said: "Eat with confidence in God and trust in Him." Ibn Majah transmitted it.
