Mu'aaz bin Jabal(Radhi:)

According to this hadith,we should not spare the rod in checking the children from becoming reckless in doing anything they like.Sometimes it is necessary to use the beginning and, when the   children get spoilt,we cry and complain about them. To spare the rod and to spoil the child is surgical operation under advice from a doctor for the  simple reason that it would cause pain to him?The Prophet( Sallallaho alaihe wasallam) is reported to have said very often: "Enjoin salaat on your child when he is seven years old,and beat him if he neglects it after he reaches ten."Hadhrat Abdullah bin Mas'ood (Radhiyallaho anho)says, "Guard the salaat of your children and inculcate good habits in them".Luqmaan the wise used to, "The use of the rod on a child is as indispensable as is water for the fields. "The Prophet(Sallallaho alaihe wasallam) is reported to have said. "A person while admonishing his children earns more reward from Allah than when he is spending about seven pounds of grain in His path."In another hadith the Prophet  (Sallallaho alaihe wasallam) has said. "May Allah bless a person who keeps a lash hanging in his house for the admonishing of his house- folk."On another occasion he said. "No father can bestow anything better on his children than to teach them good manners. "
