Yahya related to me from Malik from Yahya ibn Said that Said ibn al-Musayyub said, "Ibrahim, may Allah bless him and grant him peace, was the first to give hospitality to the guest and the first person to be circumcised and the first person to trim the moustache and the first person to see grey hair. He said, O Lord! What is this? Allah the Blessed, the Exalted, said, It is dignity, Ibrahim. He said, Lord, increase me in dignity! "
