Beyond imagination
The Hadith mentions: None of the dwellers of Heaven or Earth know about the coolness of her eyes she (a woman) will get for her labor pains. She receives for every suck of the child and every mouthful of milk the reward of a good deed. If she is kept awake by her child during the night she receives the reward of freeing 70 slaves for the sake of Allah.
