Abdullah ibn Ahmad said: Salt ibn Mas'ud al-Jahdari narrated to me, he said: Muhammad ibn Abd al-Rahman al-Tufawi narrated to us, he said: I heard al-'As ibn 'Amr al-Tufawi say: Abu al-Gadiyah, Habib ibn al-Harith, and Umm al-Gadiyah went out as emigrants to the Messenger of Allah, may Allah bless him and grant him peace, and they accepted Islam. The woman said: "Advise me, O Messenger of Allah." He said: "Beware of that which displeases the ear."
