IMPORTANT CORRECTIONS..
1. fertilisation occurs in ampulla (not ampullary-isthmic junction) NCERT correction
2. in the event of fertilization of human 'complete' sperm enters inside ovum (not only it's pronuclei)
3.karyogamy is fusion of pronuclei and amphimixis is intermingling of their chromosomes..

Human creation in quran
Surah Al-Mumenoon, Verse 12:
وَلَقَدْ خَلَقْنَا الْإِنسَانَ مِن سُلَالَةٍ مِّن طِينٍ

We have created man from an extract of clay.
Surah Al-Mumenoon, Verse 13:
ثُمَّ جَعَلْنَاهُ نُطْفَةً فِي قَرَارٍ مَّكِينٍ

Then We made him a sperm-drop in a firm resting place
Surah Al-Mumenoon, Verse 14:
ثُمَّ خَلَقْنَا النُّطْفَةَ عَلَقَةً فَخَلَقْنَا الْعَلَقَةَ مُضْغَةً فَخَلَقْنَا الْمُضْغَةَ عِظَامًا فَكَسَوْنَا الْعِظَامَ لَحْمًا ثُمَّ أَنشَأْنَاهُ خَلْقًا آخَرَ فَتَبَارَكَ اللَّهُ أَحْسَنُ الْخَالِقِينَ

Then We turned the sperm-drop into a clot, then We turned the clot into a fetus lump, then We turned the fetus lump into bones and We clothed the bones with flesh; thereafter We developed it into another creature. So, glorious is Allah, the Best of the Creators.
