"Why do you do that?" We said: "A man may have a wife, and he has intercourse with her, but he does not want her to get pregnant, or he may have a concubine, and he has intercourse with her, but he does not want her to get pregnant." He said: "It does not make any difference if you do that, for it is the matter of Al-Qadr." (Using translation from Nasāʾī 3327)
ذُكِرَ ذَلِكَ عِنْدَ رَسُولِ اللهِ ﷺ قَالَ «وَمَا ذَاكُمْ» قُلْنَا الرَّجُلُ تَكُونُ لَهُ الْمَرْأَةُ تُرْضِعُ فَيُصِيبُ مِنْهَا فَيُصِيبُهَا وَيَكْرَهُ أَنْ تَحْمِلَ مِنْهُ وَتَكُونُ لَهُ الْجَارِيَةُ فَيُصِيبُ مِنْهَا وَيَكْرَهُ أَنْ تَحْمِلَ مِنْهُ قَالَ «لَا عَلَيْكُمْ أَنْ لَا تَفْعَلُوا فَإِنَّمَا هُوَ الْقَدَرُ»
