Sauda, by Allah, you cannot conceal from us. Therefore, be careful when you go out. She ('A'isha) said: She turned back. Allah's Messenger (ﷺ) 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 ('A'isha) 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."
Sahih Muslim Book 39, Hadith 23
