Hadith 828:9
Rawh narrated to us, Qurrah ibn Khalid narrated to us, he said: I heard Mu’awiyah ibn Qurrah narrating from his father, he said: "I came to the Prophet, may Allah bless him and grant him peace, and I asked his permission to put my hand into his shirt collar so that he might pray for me. He did not prevent me, and while I was touching him, he prayed for me." He said: "And I found upon the protrusion of his shoulder something like a lump."
حدثنا روح، حدثنا قرة بن خالد، قال: سمعت معاوية بن قرة، يحدث عن أبيه، قال: " أتيت النبي صلى الله عليه وسلم فاستأذنته أن أدخل يدي في جربانه ليدعو لي، فما منعه وأنا ألمسه أن دعا لي، قال: فوجدت على نغض كتفه مثل السلعة "
