Sahih Muslim | Book 26 | Chapter 7

Narrated by 'Aisha
'Aisha reported that Sauda (Allah he pleated with her) went out (in the fields) in order to answer the call of nature even after the time when veil had been prescribed for women. She had been a bulky lady, significant in height amongst the women, and she could not conceal herself from him who had known her. 'Umar b. Khattab saw her and said: Sauda, by Allah, you cannot conceal from us. Therefore, be careful when you go out. She ('Aisha) said: She turned back. Allah's Messenger (may peace be upon him) was at that time in my house having his evening meal and there was a bone in his hand. She (Sauda) cline and said: Allah's Messenger. I went out and 'Umar said to me so and so. She ('Aisha) reported: There came the revelation to him and then it was over; the bone was then in his hand and he had not thrown it and he said: "Permission has been granted to you that you may go out for your needs.

Narrated by Hisham

Narrated by 'Aisha
'Aisha reported that the wives of Allah's Messenger (may peace be upon him) used to go out in the cover of night when they went to open fields (in the outskirts of Medina) for

easing themselves. 'Umar b Khattab used to say: Allah's Messenger, ask your ladies to observe veil, but Allah's Messenger (may peace be upon him) did not do that. So there went out Sauda, daughter of Zarn'a, the wife of Allah's Messenger (may peace be upon him), during one of the nights when it was dark. She was a tall statured lady. 'Umar called her saying: Sauda, we recognise you. (He did this with the hope that the verses pertaining to veil would be revealed). 'Aisha said: Allah, the Exalted and Glorious, then revealed the verses pertaining to veil.
