Silsilah as-Sahihah 89 — How does a sinner lose faith?

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him), he says that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When a servant commits adultery, the light of faith departs from him and hovers above him like a canopy. When he refrains, faith returns to him."
