It was narrated from ‘Abdur-Rahman bin ‘Uqbah bin Fakih bin Sa’d, from his grandfather Fakih bin Sa’d, who was a Companion of the Prophet ﷺ that the Messenger of Allah ﷺ used to take a bath on the Day of Fitr, the Day of Nahr, and the day of ‘Arafah, and Fakih used to tell his family to have a bath on these days. (Using translation from Ibn Mājah 1316)   

أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَغْتَسِلُ يَوْمَ الْجُمُعَةِ وَيَوْمَ عَرَفَةَ وَيَوْمَ الْفِطْرِ وَيَوْمَ النَّحْرِ قَالَ وَكَانَ الْفَاكِهُ بْنُ سَعْدٍ يَأْمُرُ أَهْلَهُ بِالْغُسْلِ فِي هَذِهِ الْأَيَّامِ
