"he frowned", title of surah 80 in the Qur'an.

"It is said that a blind man, named `Abdu 'llah ibn Umm Maktum, once interrupted Muhammad in conversation with certain chiefs of Quraish. The Prophet, however, took no notice of him, but frowned and turned away; and in the first verse of the Surah, he is represented as reproved by God for having done so." (Hughes's Dictionary, p.1)
