Hadith 17:583
Mu'tamir ibn Sulayman narrated to us, from Kahmas, who said: Abdullah ibn Muslim ibn Yasar said to me—or it was made binding upon me—that I should not begin with him in the book, for he does not begin except with "Amin," and a man begins with his father.
حدثنا معتمر بن سليمان عن كهمس قال قال لي عبد الله بن مسلم بن يسار أو حرج علي ألا أبدأ به في الكتاب فإنه لا يبدأ إلا بآمين ويبدأ الرجل بأبيه
