Volume 1, Book 4, Number 148:
Narrated ‘Aisha:
The wives of the Prophet used to go to Al-Manasi, a vast open place (near Baqia at Medina) to an –
swer the call of nature at night. ‘Umar used to say to the Prophet “Let your wives be veiled,” but Al –
lah’s Apostle did not do so. One night Sauda bint Zam’a the wife of the Prophet went out at ‘Isha’ time
and she was a tall lady. ‘Umar addressed her and said, “I have recognized you, O Sauda.” He said so,
as he desired eagerly that the verses of Al-Hijab (the observing of veils by the Muslim women) may
be revealed. So Allah revealed the verses of “Al-Hijab” (A complete body cover excluding the eyes).
