Jami` at-Tirmidhi, Book 47, Hadith 3508 (In-Book)

Narrated Musa and 'Eisa, the sons of Talhah: from their father: "The Companions of the Prophet 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, 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 said: 'This is one who has fulfilled his vow.'"

حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا يُونُسُ بْنُ بُكَيْرٍ، عَنْ طَلْحَةَ بْنِ يَحْيَى، عَنْ مُوسَى، وَعِيسَى، ابْنَىْ طَلْحَةَ عَنْ أَبِيهِمَا، طَلْحَةَ أَنَّ أَصْحَابَ، رَسُولِ اللَّهِ صلى الله عليه وسلم قَالُوا لأَعْرَابِيٍّ جَاهِلٍ سَلْهُ عَمَّنْ قَضَى نَحْبَهُ مَنْ هُوَ وَكَانُوا لاَ يَجْتَرِئُونَ عَلَى مَسْأَلَتِهِ يُوَقِّرُونَهُ وَيَهَابُونَهُ فَسَأَلَهُ الأَعْرَابِيُّ فَأَعْرَضَ عَنْهُ ثُمَّ سَأَلَهُ فَأَعْرَضَ عَنْهُ ثُمَّ سَأَلَهُ فَأَعْرَضَ عَنْهُ ثُمَّ إِنِّي اطَّلَعْتُ مِنْ بَابِ الْمَسْجِدِ وَعَلَىَّ ثِيَابٌ خُضْرٌ فَلَمَّا رَآنِي رَسُولُ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ أَيْنَ السَّائِلُ عَمَّنْ قَضَى نَحْبَهُ ‏"‏ ‏.‏ قَالَ الأَعْرَابِيُّ أَنَا يَا رَسُولَ اللَّهِ ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ هَذَا مِمَّنْ قَضَى نَحْبَهُ ‏"‏ ‏.‏ قَالَ هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ لاَ نَعْرِفُهُ إِلاَّ مِنْ حَدِيثِ يُونُسَ بْنِ بُكَيْرٍ ‏.‏
