Narrated Musa and 'Eisa, the sons of Talhah: from their father: "The Companions of the Prophet (ﷺ) said, to an unknowing Bedouin man: 'Ask him who it is that has fulfilled his vow.' They were not in the habit of asking questions out of their respect and reverence for him. So the Bedouin asked him, but he turned away from him. Then he asked him again, but he turned away from him. Then again he asked him, but he turned away from him. Then I stood looking from the door of the Masjid, while I was wearing a green garment, and I saw the Prophet (ﷺ), he said: 'Where is the one who was asking about the one who fulfilled his vow?' The Bedouin said: 'Here I am O Messenger of Allah!' The Messenger of Allah (ﷺ) said: 'This is one who has fulfilled his vow.'"
