It has been reported that once in the course of his journey, one of the Prophets came across a small stone and observed that a large quantity of water flowed out from it. As the incident left him greatly astonished, Allah made speech come out from the stone, which said: “Ever since I heard that men and stones would be the fuel of the fire of Hell, I have been in a state of weeping (out of fear that I should be one of those stones).”
The stone then requested the Prophet to pray that it should remain protected from the fire (of Hell) and the Prophet, acceding to his request, prayed for it.
It so happened that after a period, the Prophet again passed by that place and, witnessing that the water still continued to flow from the stone as before, inquired: “What is it that makes you weep now?”
The stone replied, “Before I could be satisfied of my deliverance from the fire (of Hell), my tears were out of fear, but now, I weep out of thanksgiving and due to joy and happiness.”( Shanidani-ha-e Tarikh, Page 388; Mahajjatul Baiďa, Volume 7, Page 142 )
