It is reported on the authority of Al-Wakî’ b. Al-Jarrâh:
We went out one Eid with Sufyân Al-Thawrî and he said,
“The first thing we will do on this day of ours is to lower our gaze.”
Ibn Abî Al-Dunyâ, Kitâb Al-Wara’. article 66.
It is reported that Hassân b. Abî Sinân – Allâh have mercy on him – went out one Eid and when he returned home his wife said, “How many beautiful women have you looked at today?” After she kept asking him, he said, “Woe to you! I have looked at nothing but my toe from when I went out to when I returned to you.”
Ibn Abî Al-Dunyâ, Kitâb Al-Wara’. article 68.
