Growth of a Child

“Abu ‘Abd Allah (a.s.), has stated this Hadith. ‘Children’s milk teeth are replaced in seven years. They must be instructed to perform Salat (prayer) at the age of nine years, their bed must be separated at the age of ten, they experience wet dream at the age of fourteen, their growth in length stops at the age of twenty-two and their growth of reason stops at the age twenty-eight except experiences.’”

“Abu ‘Abd Allah (a.s.), has said that ’Amir al-Mu’minin (a.s.), has said, ‘A child grows every year by four fingers of his own fingers.’”

“Abu ‘Abd Allah (a.s.), has narrated from his father (a.s.), who has said, that a boy cannot impregnate until his breast becomes round and the smell of his armpit rises strong.’”
