Hazrat Ubaidullah bin Ubaid al-Kala'i (may Allah have mercy on him) narrates that Hazrat Mak'hool (may Allah have mercy on him) held my hand and said: O Abu Wahb (may Allah have mercy on him)! Increase the greatness of faith within yourself. Whoever deliberately abandons an obligatory prayer, indeed Allah's protection is absolved from him, and whoever is absolved of Allah's protection, indeed he has committed disbelief.
