Abu Bakr ibn ‘Ayyaash said:

I prayed [the] Maghrib [prayer] behind Fudhayl ibn ‘Iyaadh, with his son ‘Alee at my side. He (Fudhayl) recited:

{Competition in [worldly] increase diverts you} [- soorah at-Takaathur]

…and when he recited [the verse]:

{You will surely see the Hellfire}

…‘Alee [was overcome and] fell unconscious – on his face.
