It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: If a believer were to know of the punishment (torment) prepared by Allah Almighty, no one would hope for Paradise. And if a disbeliever were to know of the vastness of Allah Almighty’s mercy, no one would despair of His Paradise.
