How should a Muslim deal with one who neglects the prayer?

Question:
He says: There is a person who claims to be a Muslim, and he prays some of the prayers and leaves off others. He says: How should I deal with him?

Answer:
Deal with him as one who neglects the prayer, that he deliberately leaves off the prayer, even if it is some of the prayers, even if it is some of the prayers, he deliberately leaves them off. This is disbelief. You inform him of that. The Messenger (peace and blessings be upon him) said:
And when the people of the Fire are asked on the Day of Resurrection, “What led you into the Fire?” What is their first answer? “We were not among those who prayed.” This is the first answer they give: meaning they do not pray and they do not give charity. These are two of the pillars of Islam, and they do not believe in the Hereafter. We used to engage in idle talk with those who engaged in it. They would say, “Perhaps there will be a resurrection, and perhaps there will not.” This idle talk is what put them into the Fire, may Allah protect us from it. Yes.
