Tradition says that he memorized the Qur’an at the age of seven; by ten, he had memorized the Muwatta of Malik ibn Anas; he was a mufti (given authorization to issue fatwa) at the age of fifteen. He recited the Qur'an every day in prayer, and twice a day in Ramadan. Some apocryphal accounts claim he was very handsome, that his beard did not exceed the length of his fist, and that it was very black. He wore a ring that was inscribed with the words, "Allah suffices Muhammad ibn Idris as a reliance." He was also known to be very generous.
