إِنَّ لِلرَّحِمِ أَرْبَعَةَ سُبُلٍ فِي أَيِّ سَبِيلٍ سَلَكَ فِيهِ الْمَاءُ كَانَ مِنْهُ الْوَلَدُ وَاحِدٌ وَ اثْنَانِ وَ ثَلَاثَةٌ وَ أَرْبَعَةٌ وَ لَا يَكُونُ إِلَى سَبِيلٍ أَكْثَرُ مِنْ وَاحِدٍ.
‘The womb has four ways in whichever way the seed (water) finds the path thereof comes a child, one child, two children , three children or four children . In (through) one way only one child can come and no more/”
إِنَّ اللَّهَ عَزَّ وَ جَلَّ خَلَقَ لِلرَّحِمِ أَرْبَعَةَ أَوْعِيَةٍ فَمَا كَانَ فِي الْأَوَّلِ فَلِلْأَبِ[1] وَ مَا كَانَ فِي الثَّانِي فَلِلْأُمِّ وَ مَا كَانَ فِي الثَّالِثِ فَلِلْعُمُومَةِ وَ مَا كَانَ فِي الرَّابِعِ فَلِلْخُئُولَةِ.
“Abu ‘Abd Allah (a.s.), has said, ‘Allah has created four receptacles for the womb. Whatever is from the first is for the father, whatever is from the second is from the mother, whatever is from the third is from the paternal uncles and whatever is from the fourth is from the maternal uncles (in gender or shape).’”
