Ayesha reported,

Sawda went out after the verse of veiling had been revealed, attending to a need of hers. She was a large woman, easily recognized by anyone who knew her. Umar bin Khattab saw her and said, "Sawda, by Allah, you are not hidden from us. So consider carefully how you go out."She turned back at once. The Messenger of Allah ﷺ was in my house at the time, eating his dinner, with a bone in his hand. She came in and said, "Messenger of Allah, I went out to attend to a need of mine, and Umar said such and such to me."Then Allah revealed something to him, and when the revelation lifted from him, the bone was still in his hand. He had not put it down. He said, "Permission has been granted for you to go out to attend to your needs."

حدثني زكرياء بن يحيى حدثنا أبو أسامة عن هشام عن أبيه

عن عائشة رضي الله عنها قالت

خرجت سودة بعدما ضرب الحجاب لحاجتها وكانت امرأة جسيمة لا تخفى على من يعرفها فرآها عمر بن الخطاب فقال يا سودة أما والله ما تخفين علينا فانظري كيف تخرجين قالت فانكفأت راجعة ورسول الله ﷺ في بيتي وإنه ليتعشى وفي يده عرق فدخلت فقالت يا رسول الله إني خرجت لبعض حاجتي فقال لي عمر كذا وكذا قالت فأوحى الله إليه ثم رفع عنه وإن العرق في يده ما وضعه فقال إنه قد أذن لكن أن تخرجن لحاجتكن

His saying, "Do not enter the houses of the Prophet except when you are permitted for a meal, without awaiting its readiness. But when you are invited, then enter; and when you have eaten, disperse and do not seek to remain for conversation. Indeed, that was troubling the Prophet, and he is shy of you, but Allah is not shy of the truth. And when you ask them for something, ask them from behind a partition. That is purer for your hearts and their hearts. And it is not for you to trouble the Messenger of Allah or to marry his wives after him ever. Indeed, that would be, in the sight of Allah, an enormity."
