It is narrated from Sayyidah Aishah (may Allah be pleased with her): "The Messenger of Allah (peace and blessings be upon him) had two (particular) garments which he (peace and blessings be upon him) used to wear on Friday; then, when he (peace and blessings be upon him) finished (the Friday prayer) and returned, he would fold them up and put them away."
Imam al-Harith recorded this hadith in his Musnad (710); its chain contains the narrator Muhammad bin Umar al-Waqidi, who is da'if (weak). However, on the basis of other supporting reports and narrations, wearing fine clothing for Friday has a sound basis.
