“When the number of Emigrants to Medina grew and they had no house or shelter, the Messenger of Allah ﷺ lodged them in the mosque and named them the People of the Ṣuffa. He would sit with them and find comfort in their company. (The ṣuffa was a shaded section inside the Prophet’s Mosque.) Thus it appears in Fatḥ al-Bārī.
(c) ʿĀʾishah (may Allah be pleased with her) reported:
A young slave-girl, dark-skinned, belonged to an Arab tribe. They set her free, so she stayed with them. One day a little girl of theirs went out wearing a red sash made of leather thongs. She put it down—or it slipped off her—and a kite flew past, saw it lying there, thought it was meat, and carried it off. They looked for the sash but could not find it, so they accused me of taking it and began searching, even to the point of inspecting my private parts. By Allah, I was standing with them when the kite passed overhead again and dropped the sash; it fell right among them. I said, ‘This is the thing you accused me of! You claimed I had taken it, yet I am innocent—here it is.’ After that she went to the Messenger of Allah ﷺ and embraced Islam.
ʿĀʾishah continued: She had a small tent—or a rough shelter—in the mosque, and she used to come to me and talk with me. Never would she sit in my presence without saying:
“The day of the sash—one of our Lord’s wonders;
From the land of disbelief He delivered me.”
I asked her, ‘Why is it that every time you sit with me you recite those lines?’ She then told me this story.
Al-Bukhārī recorded the narration through the route of Abū Usāmah, from Hishām, from his father, from her, with this wording.
