Jami` at-Tirmidhi 2479
Abu Burdah bin Abi Musa narrated that his father said:
"O my son! If you saw us when we were with the Prophet(s.a.w) and the sky poured upon us, you would think that our smell was the smell of sheep." The meaning of this Hadith
is that their garments were of wool,
so when the rain fell upon them,
the smell coming from their clothes
was that of sheep.
حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ قَتَادَةَ، عَنْ أَبِي بُرْدَةَ بْنِ أَبِي مُوسَى، عَنْ أَبِيهِ، قَالَ يَا بُنَىَّ لَوْ رَأَيْتَنَا وَنَحْنُ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَأَصَابَتْنَا السَّمَاءُ لَحَسِبْتَ أَنَّ رِيحَنَا رِيحُ الضَّأْنِ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ صَحِيحٌ ‏.‏ وَمَعْنَى هَذَا الْحَدِيثِ أَنَّهُ كَانَ ثِيَابَهُمُ الصُّوفُ فَكَانَ إِذَا أَصَابَهُمُ الْمَطَرُ يَجِيءُ مِنْ ثِيَابِهِمْ رِيحُ الضَّأْنِ ‏.‏
