He who will be having the quality of Islam and will be particular in performing Salat regularly, will raise a wall between himself and Kufr. He who does not perform Salat after coming to the fold of Islam, does not have a frontier which separates him from infidelity. Leaving Salat is like demolishing the wall that separates Islam from Kufr. Thus, we learn from this Hadith that leaving Salat is Kufr. Some `Ulama' are of the opinion that this injunction is for one who believes leaving Salat is permissible whereas the one who leaves it because of slackness is not Kafir. Some scholars, however, think that if such a person does not repent, he is liable to Hadd, i.e., death punishment. There are other `Ulama' who think that rather than death punishment such a person should be subjected to corporal punishment till he starts offering Salat. This Hadith makes the importance of Salat in Islam abundantly clear.
