"My wife is breast-feeding and I do not want her to get pregnant." The Prophet said: "What has been decreed in the womb will come to be." (Using translation from Nasāʾī 3328)

أَنَّ رَجُلًا سَأَلَ النَّبِيَّ ﷺ عَنِ الْعَزْلِ فَقَالَ إِنَّ امْرَأَتِي تُرْضِعُ وَأَنَا أَكْرَهُ أَنْ تَحْمِلَ فَقَالَ النَّبِيُّ ﷺ «إِنَّ مَا قُدِّرَ فِي الرَّحِمِ سَيَكُونُ»
