It is reported that ‘Awn b. ‘Abdillâh – Allâh have mercy on him – said:
Those before you used to give to their worldly affairs what was left over from their pursuit of the hereafter. But today, you give to the matters of the hereafter the left-overs from your pursuit of worldly affairs.
Abû Nu’aym, Hilyat Al-Awliyâ` 10:242.
