It is narrated from Hazrat Abu Hurairah, may Allah be pleased with him, that once the companions, may Allah be pleased with them, said, "O Messenger of Allah, peace and blessings be upon him, sometimes such thoughts come into our hearts that we do not like to utter them, even if we were to be given the whole world in exchange." The Noble Prophet, peace and blessings be upon him, said, "Does this really happen?" The companions, may Allah be pleased with them, replied, "Yes." The Noble Prophet, peace and blessings be upon him, said, "This is pure faith."
