Sunan an-Nasa'i 189
Abu Hurairah said:
"Thumamah bin Uthal Al-Hanafi went to fetch some water that was near the Masjid and performed Ghusl, then he entered the Masjid and said: 'Ashhadu an la ila ha ill-Allah was ashhadu anna Muhammadan 'abduhu wa rasuluh (I bear witness that there is none worthy of worship except Allah and I bear witness that Muhammad is His slave and Messenger), O Muhammad, by Allah! There was no face on the face of the Earth that was more hateful to me than your face, not now your face has become the most beloved of all faces to me. You cavalry captured me and I want to perform 'Umrah. What do you think? The Prophet (ﷺ) gave him glad tidings and told him to perform 'Umarah."
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ، أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ، يَقُولُ إِنَّ ثُمَامَةَ بْنَ أُثَالٍ الْحَنَفِيَّ انْطَلَقَ إِلَى نَجْلٍ قَرِيبٍ مِنَ الْمَسْجِدِ فَاغْتَسَلَ ثُمَّ دَخَلَ الْمَسْجِدَ فَقَالَ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ يَا مُحَمَّدُ وَاللَّهِ مَا كَانَ عَلَى الأَرْضِ وَجْهٌ أَبْغَضَ إِلَىَّ مِنْ وَجْهِكَ فَقَدْ أَصْبَحَ وَجْهُكَ أَحَبَّ الْوُجُوهِ كُلِّهَا إِلَىَّ وَإِنَّ خَيْلَكَ أَخَذَتْنِي وَأَنَا أُرِيدُ الْعُمْرَةَ فَمَاذَا تَرَى فَبَشَّرَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم وَأَمَرَهُ أَنْ يَعْتَمِرَ ‏.‏ مُخْتَصِرٌ ‏.‏
