Sayyidah Aishah (may Allah be pleased with her) narrates from Sayyidah Judamah bint Wahb al-Asadiyyah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) intended to forbid ghiyal (intercourse during the nursing period), but then he said: "I looked and found that the Persians and the Romans do so, and it does not harm their children." She related that the Messenger of Allah (peace and blessings be upon him) was asked about 'azl (withdrawal), and he (peace and blessings be upon him) said: "It is a hidden burying alive (al-wa'd al-khafi)." The two Shaykhs (Bukhari and Muslim) have recorded this hadith through the chain of Imam Malik without the addition, while this addition is in the narration of Yahya bin Ayyub.
