وَعَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ أَنَّ نَبِيَّ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ ”إِذَا اشْتَهَى الْمُؤْمِنُ الْوَلَدَ فِي الْجَنَّةِ كَانَ حَمْلُهُ وَوَضْعُهُ وَسِنُّهُ فِي سَاعَةٍ وَاحِدَةٍ كَمَا يَشْتَهِي“
It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: When any believer in Paradise wishes for a child, its conception, birth, and attainment of the desired and preferred age—all these stages will occur in an instant.
