Sex determination as given by  Prophet Muhammad

        Recent Scientific knowledge  have provided a proof to the  hadeeth (a prophet Muhammad talk) in which he gives us a hint about the manner by which one sex prevails.   According to this hadeeth , reported by thauban  ,  when a Jew asked him about  child creation ,  He answered him :  male fluid is white and female fluid is yellow  , when they mix & male fluid prevails , they , with God permission , produce a male child  , but if female fluid prevails , they , with God permission , produce a female child  . ( This is  a part of a long hadeeth , narrated by   Saheeh Muslim ,  Al-Hyeed (Menstruation ) book , 315)

        If we notice the previous fact carefully , it will be clear that prophet Muhammad , Peace and blessings be upon him ,  gave in a clear cut answer that determination of child sex  occurs by participation of both partners , and  the coming  child acquire the sex of the parent whose (genital) fluid prevails . Explaining this hadeeth , shows that it represents a scientific miracle added to the prophet  miracles , first ; it clearly describes the color of male fluid of being white and that of female of being yellow . One could say that the color of male fluid is easily seen in males , but , no one knows that female has a  fluid . According to science , the female genital fluid that corresponds to male fluid is the fluid carrying ovum when it is ejected from the ovary at time of ovulation , this fluid is yellowish in color . Does any one , at that time , knows any idea about this !!!!

      The first step in human creation is union between a sperm from male and an ovum from female , the sex of embryo belongs , according to previous hadeeth , to the prevailing fluid . As it is known now that ovum is one type ; containing an x-chromosome , but sperms occur in 2 types , X- chromosome carrying sperm & Y-chromosome carrying sperm . It was described that sex of embryo is determined according to type of sperm that fertilizes the ovum : if a Y-carrying sperm fertilizes the ovum , a male child is produced & when X- carrying sperm fertilizes the ovum , a female child is produced. In other wards , male is the one  who is responsible for sex determination . The previous hadeeth determines that participation of both parents is required to determination of sex  .

        Recent advances in fertilization studies  showed that  sex determination is an electric phenomenon , the ovum has an electrical polarity cycle with a changing  electrical charge ( positive , neutral , negative) , also Y-carrying sperm has a positive charge &  X- carrying sperm has a negative charge .When the ovum is negatively charged , it unites with Y-carrying sperm with the  positive charge  and a male child is produced .  When the ovum is  positively  charged , it unites with X- carrying sperm with the  negative  charge  and a female child is produced . Thus , the coming child acquires the sex of the gamete (sperm or ovum) that has a positive charge .

         According to basics  of electricity ,  the positive charge is the prevalent  or the stronger and this fact  is in amazing accordance with the hadeeth of prophet Muhammad and proves not only the truth of this hadeeth , but also gives an evidence to his prophethood who had told these  facts since 1500 years because  in Arabic the term prevail means  overcomes or conquers ,  and it becomes clear that the gamete that has the positive charge overcomes the negative one & the child will have the sex of the prevailing gamte . Thus , male and female share each other in determination of the sex of the coming offspring  in accordance with the prophet's hadeeth.

         Although  these scientific facts informs us about the way by which  one sex  is determined , this does not mean that we become able to have the child we desire , Allah , the Almighty ,  in the noble Qur'an  said:

"لله ملك السموات والأرض  يخلق ما يشاء يهب لمن يشاء إناثاً ويهب لمن يشاء الذكور أو يزوجهم ذكرناً وإناثا ويجعل من يشاء عقيما  إنه عليم قدير "

 "Unto Allah belongeth the sovereignty of the heavens and the earth .He createth what He will. He bestoweth female (offspring) upon whom He will , and bestoweth male (offspring) upon whom He will  ; or He mingleth them , males and females , and He maketh barren whom He will . Lo!He is Knower ,Powerful  "( Al-Shura , 42 : Ayat 49-50)
