Malik related to me from Abdullah ibn Abi Bakr from his father that the Messenger of Allah, may Allah bless him and grant him peace, said, "If a man sneezes, invoke a blessing on him. Then if he sneezes, invoke a blessing on him. Then if he sneezes, invoke a blessing on him. Then if he sneezes, say, You have a cold." Abdullah ibn Abi Bakr said, "I dont know whether it was after the third or fourth."
