Ibn al-Qayyim:
(May Allāh have mercy on him)
*Fear of A Bad Ending*
“Sufyān al-Thawrī, may Allāh have mercy on him, once cried a whole night until the morning, so in the morning he was asked if his cry was due to the fear of sins.
He picked hay from the ground and said:
‘Sins are lighter than this hay, I only cried out of fear of the bad ending.’
Ibn al-Qayyim said: And this is the peak of Fiqh (knowledge and understanding) that a man fears that his sins let him down at the time of death and that they come between him and the good ending.”
