I heard the Prophet صلى الله عليه وآله say: Whoever fasts one day from [the month] of Rajab, with faith (‘Imān) and contentment, Allāh, Blessed and High, makes for him seventy trench (i.e. a barrier) between himself and the fire. The width of every trench is that of the distance between the Heavens and the Earth.
