The creation of a person
إِنَّ أَحَدَكُمْ يُجْمَعُ خَلْقُهُ فِي بَطْنِ أُمِّهِ أَرْبَعِينَ يَوْمًا نُطْفَةً، ثُمَّ يَكُونُ عَلَقَةً مِثْلَ ذَلِكَ، ثُمَّ يَكُونُ مُضْغَةً مِثْلَ ذَلِكَ، ثُمَّ يُرْسَلُ إِلَيْهِ الْمَلَكُ فَيَنْفُخُ فِيهِ الرُّوحَ
Inna ahadakum yujma'u khalquhu fi batni ummihi arba'ina yawman nutfah, thumma yakunu 'alaqatan mithla dhalik, thumma yakunu mudghatan mithla dhalik, thumma yursalu ilayhi-l-malaku fa-yanfukhu fihi-r-ruh.
"Each of you is gathered in the womb of his mother for forty days as a drop, then a clinging form for the same period, then a morsel of flesh for the same period; then an angel is sent to him and breathes the soul into him."
Narrated by Abdullah ibn Mas'ud. Sahih al-Bukhari 3208, Sahih Muslim 2643 · Nawawi's Forty · #4
A short reflection
Four stages. The soul is a gift breathed in from outside of time — every body is, in that sense, borrowed.
