The Messenger of Allah ﷺ took a man who was suffering from tubercular leprosy by the hand; he then put it along with his own hand in the dish and said: Eat with confidence in Allah and trust in Him. (Using translation from Abū Dāʾūd 3925)
أَنَّ النَّبِيَّ ﷺ أَخَذَ بِيَدِ مَجْذُومٍ فَوَضَعَهَا مَعَهُ فِي الْقَصْعَةِ ثُمَّ قَالَ «بِسْمِ اللَّهِ ثِقَةً بِاللَّهِ وَتَوَكُّلًا عَلَيْهِ»
