Four types of oceans

There are four types of oceans: The ocean of sins, the self (nafs) is the ocean of lust, death is the ocean of life and the grave is the ocean of distress. [Umar (RA)]

"You who commit a sin, do not feel secure about the results, for what goes along with the sin is more serious than the sin itself.
Your lack of shame before the angels, who witness you when you commit the sin, is more serious than the sin itself.
Your laughter when you sin, as you forget the punishment of Allah is more serious than the sin itself.
Your delight if you get a chance to sin, is more serious than the sin itself.
Even your disappointment, if you miss a chance to sin is more serious than the sin itself."
Our Righteous Predecessors were as fearful of their good deeds being squandered, or not being accepted, as the present generation is certain that their neglect would be forgiven. [Hasan al Basri (RA)]

O people who take pleasure in a life that will vanish, falling in love with a fading shadow is sheer stupidity [Ibn al-Qayyim]
