Narrated Judamah (RA) daughter of Wahb: I was with Allah's Messenger ( صلی اللہ علیہ وسلم ) along with some people when he was saying, "I have intended to prohibit Ghila (sexual intercourse with a woman who is breast-feeding), but I considered the Romans and the Persians and saw that they engaged in Ghila without any injury being caused to their children thereby." Then they asked him about 'Azl (withdrawing the penis before emission of semen, to avoid conception), and Allah's Messenger ( صلی اللہ علیہ وسلم ) replied, "That is the secret (way of) burying alive."
