Mishkat al-Masabih 4585
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.
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
