"I heard the Messenger of Allah say: 'I wanted to forbid intercourse with a nursing mother, but then (I saw that) the Persians and the Romans do this, and it does not kill their children.' And I heard him say/when he was asked about coitus interruptus: 'It is the disguised form of b.rryirg children alive."
أَنَّهَا قَالَتْ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ قَدْ أَرَدْتُ أَنْ أَنْهَى عَنِ الْغِيَالِ فَإِذَا فَارِسُ وَالرُّومُ يُغِيلُونَ فَلاَ يَقْتُلُونَ أَوْلاَدَهُمْ وَسَمِعْتُهُ يَقُولُ وَسُئِلَ عَنِ الْعَزْلِ فَقَالَ هُوَ الْوَأْدُ الْخَفِيُّ
