"A man from among the Ansar came to the Prophet ﷺ and said: 'O Messenger of Allah ﷺ, I have a slave girl. Should I do 'Azl (coitus interruptus) with her?' He said 'Whatever is decreed for her shall come to her." He (the Ansari) came to him later on and said: "The slave girl has become pregnant." The Prophet ﷺ said: "Nothing is decreed for a person but it will surely come to pass."
جَاءَ رَجُلٌ مِنَ الأَنْصَارِ إِلَى النَّبِيِّ ﷺ فَقَالَ يَا رَسُولَ اللَّهِ إِنَّ لِي جَارِيَةً أَعْزِلُ عَنْهَا قَالَ سَيَأْتِيهَا مَا قُدِّرَ لَهَا فَأَتَاهُ بَعْدَ ذَلِكَ فَقَالَ قَدْ حَمَلَتِ الْجَارِيَةُ فَقَالَ النَّبِيُّ ﷺ مَا قُدِّرَ لِنَفْسٍ شَىْءٌ إِلاَّ هِيَ كَائِنَةٌ
