Abu Qalaba, 'Abdullah bin Zayd al-Jarmi عبد الله بن زيد بن عمرو · The Book on Marriage

"We said: 'O Messenger of Allah! We practice Azl, but the Jews claim that it is minor infanticide.' So he said: 'The Jews lie. When Allah wants to create it, nothing can prevent Him.'"

"We practiced Azl while the Qur'an was being revealed."
