[11]. The Prophet Muhammad (may Allah's peace and blessings be upon him) said: "Two eyes will not be touched by the Fire: an eye which has wept out of fear of God, and an eye which has spent the night guarding in the cause of God."
When a person remembers the greatness of Allāh, His power over His servants, and, at the same time, he recalls his own state and his negligence in fulfilling the rights of Allāh upon him, he weeps in hope of receiving Allah's Mercy and in fear of His Wrath and Punishment. Such a person is promised to be saved from the Hellfire.
