What did the Prophet Muhammad (saw) say about those who have faith and humility in their hearts?
 It is narrated on the authority of 'Abdullah b. Mas'ud that the Messenger of Allah (may peace be upon him) observed:                      None shall enter the Fire (of Hell) who has in his heart the weight of a mustard seed of Iman and none shall enter Paradise who has in his heart the weight of a mustard seed of pride.
