Rasulullah sallallahu ‘alayhi wa sallam said: “The reward that a woman receives from the time that she falls pregnant until she delivers the child and commences breast-feeding is equal to the person who is guarding the borders of the Islamic state and who has to be ever ready to wage jihad. If this woman dies in the course of this period, she will receive the reward of a martyr.”
Rasulullah sallallahu ‘alayhi wa sallam said: “When a woman breast-feeds her child, the reward that she receives for every sip is as if she has given life to a dead person. When she commences breast-feeding, an angel taps her on her back (a form of congratulation) and says to her: ‘All your past sins are forgiven. Now whatever you do will be recorded from the very beginning.'” That is, the sins that you may commit will be written for the future. Minor sins are referred to in this context. However, having one’s minor sins forgiven is no small feat.
