'Allah, Blessed and most High, says, 'By My Honour and Majesty, I do not combine two types of fear for My servant, neither do I combine two types of security for him. If he feels secure from Me [and My Punishment] in this world, I will frighten him on the Day of Resurrection, and if he fears Me in this world, I will provide security for him on the Day of Resurrection.'
Prophet Muhammad al-Mustafa [sawa]
