In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Imaam Ibnul Qayyim [rahimahullaah] said: Shaqeeq Ibn Ibraaheem [rahimahullaah] said: The door of success and well-being are shut in front of the people due to six reasons: ”Preoccupation with the blessings of [Allaah], whilst they are ungrateful; desire for knowledge, whilst abandoning action; rushing towards sin, whilst delaying repentance; being honoured with companionship of the righteous people, whilst not following their deeds; the worldly life elapses, whilst they run after it and the afterlife is approaching them, whilst they turn away from it.”
I [i.e. Ibnul Qayyim] say: The basis of this is due to not having a fervent desire and fear, weakness in one’s certainty, short-sightedness, lowliness of the soul and exchanging that which is better for that which is lower; for if the soul [of this person] was noble, it would not have been pleased with something lower [or inferior].
