Regarding 'Azl (Withdrawing Before Ejaculation)
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا أَبَانُ، حَدَّثَنَا يَحْيَى، أَنَّ مُحَمَّدَ بْنَ عَبْدِ الرَّحْمَنِ بْنِ ثَوْبَانَ، حَدَّثَهُ أَنَّ رِفَاعَةَ حَدَّثَهُ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّ رَجُلاً، قَالَ يَا رَسُولَ اللَّهِ إِنَّ لِي جَارِيَةً وَأَنَا أَعْزِلُ عَنْهَا وَأَنَا أَكْرَهُ أَنْ تَحْمِلَ وَأَنَا أُرِيدُ مَا يُرِيدُ الرِّجَالُ وَإِنَّ الْيَهُودَ تُحَدِّثُ أَنَّ الْعَزْلَ مَوْءُودَةُ الصُّغْرَى . قَالَ " كَذَبَتْ يَهُودُ لَوْ أَرَادَ اللَّهُ أَنْ يَخْلُقَهُ مَا اسْتَطَعْتَ أَنْ تَصْرِفَهُ " .
Narrated AbuSa'id al-Khudri: A man said: Messenger of Allah, I have a slave-girl and I withdraw the penis from her (while having intercourse), and I dislike that she becomes pregnant. I intend (by intercourse) what the men intend by it. The Jews say that withdrawing the penis (azl) is burying the living girls on a small scale. He (the Prophet) said: The Jews told a lie. If Allah intends to create it, you cannot turn it away.
