1. Muhammad ibn Yahya and others have narrated from Ahmad ibn Muhammad ibn ‘Isa from Ahmad ibn Muhammad from ibn abu Nasr from ’Isma‘il ibn ‘Umar from Shu’ayb al-‘Aqarqufiy who has said the following: “Abu ‘ Abd Allah , has said, ‘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/”
