Volume 8, Book 73, Number 52:
Narrated ‘Adi bin Hatim:
The Prophet mentioned the (Hell) Fire and sought refuge (with Allah) from it, and turned his face
to the other side. He mentioned the (Hell) Fire again and took refuge (with Allah) from it and turned
his face to the other side. (Shu’ba, the sub-narrator, said, “I have no doubt that the Prophet repeated it
twice.”) The Prophet then said, “(O people!) Save yourselves from the (Hell) Fire even if with one half
of a date fruit (given in charity), and if this is not available, then (save yourselves) by saying a good
pleasant friendly word.”
