(Imām Bukhārī narrates): Abu al-Yaman narrated to us, he said: Shu'aib informed us, from al-Zuhri, he narrated that Tawus said:
I said to Hazrat Ibn Abbas (may Allāh be pleased with them both) that the people have mentioned this hadith, that the Prophet ﷺ said: Take a bath on the day of Friday and wash your heads even if you are not in a state of janabah, and apply perfume. Hazrat Ibn Abbas said: As for the bath, it is his ﷺ statement, and regarding perfume, I do not have knowledge.
حَدَّثَنَا أَبُو اليَمَانِ، قَالَ أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ طَاوُسٌ قُلْتُ لِابْنِ عَبَّاسٍ
ذَكَرُوا أَنَّ النَّبِيَّ صَلّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ اغْتَسِلُوا يَوْمَ الجُمُعَةِ وَاغْسِلُوا رُءُوسَكُمْ، وَإِنْ لَمْ تَكُونُوا جُنُبًا وَأَصِيبُوا مِنَ الطِّيبِ
