Fudayl Ibn ‘Iyaad (rahimahullah) said to ‘Aasim Al-Ahwal:

“O you! Do not allow the people’s great number of people to busy you, for indeed the final affair will only be about you besides them.

Beware of wasting your day here and there, for surely this is counted against you, and I have not seen anything more beautiful in seeking or faster in catching than a new good deed for an old bad deed.”

[Al-Hilyah, 3/102]
