Professor Ansarian pointed out about the reward of the mothers who give birth to children and said: those women who get pregnant, give birth and breastfeed their children, if they believe in Allah and the day of resurrection and also do the obligatory deeds and things, according to what the messenger of Allah has said, from the time a believer woman gets pregnant till his child is two years old and she weans her child, this woman is like someone who has prepared a horse and is fighting sincerely on the way of Allah Almighty. The reward of these thirty months of this woman equals to thirty months of Jihad and fighting on the way of Allah Almighty.
