What did the Prophet Muhammad (saw) mention regarding Fire and how did he suggest to protect oneself against it?
 'Adi b. Hatim reported that the Messenger of Allah (may peace be upon him) made a mention of Fire. He turned his face aside and diverted his attention and then said:                      Guard (yourselves) against Fire. He turned his face and diverted his attention till we thought as if he were (actually seeing it and then said: Protect yourselves against Fire even if it is with half a date, and he who does not find it, (he should do so) with pleasant words. Abu Kuraib did not mention the word: (as if).
