2. Wearing the best clothing
It was narrated by al-Bukhaaree from ‘Umar that he saw an expensive garment at the masjid and said: “O Messenger of Allah, (what) if I bought this for (you) for Jumu'ah and for delegations.”
Also, Ibn Khuzaymah narrated in his Saheeh: The Chapter of it Being Recommended for the Individual to Have Clothes for Jumu’ah Other Than Those for Work.
He narrated with his chain of narration from ‘Aa`ishah that the Prophet said: “There is no blame upon anyone of you if he found the means, to buy two thawbs (garments) for his Jumu’ah other than his two garments for work.”
