Reasons for the birth of Hijra : Hazrat Ibn Abbas (R) said: Hijras are the children of jinn. One person asked Abbas (R) how it could be. In reply, he said , "Allah and the Prophet (peace be upon him) forbade a man to have sexual intercourse with his wife during her menstrual period." . (The joint child of man and jinn is called "Khunnas" in Islam). Evidence: Surah Bani Israel - R Rahman - 54 , Ibn Abi Hatim , Hakim Tirmidhi. The XX pattern is formed from the ovum of the girl child and the XY pattern is formed from the boy child. Under the influence of chromosome patterns in the embryonic maturation stages, testicles are born in the boy and ovum in the girl. The male hormone androgen is secreted from the testicles and estrogen is secreted from the ovary. Fertilization and division during embryonic development result in a number of abnormal patterns, such as XXY or XYY . As a result, heterosexual babies of different shapes are born. For one thing , a transgender child can be cured in most cases if he or she receives proper medical treatment before reaching adulthood. But when it is understood that he is different from the ordinary and the ten, then it is actually too late. Similarly, a man or a woman can be a transgender person.
