مُوَطَّأُ مَالِكٍ
Muwatta Malik 241
Jumu'a
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، أَنَّهُ بَلَغَهُ أَنَّ رَسُولَ اللَّهِ قَالَ مَا عَلَى أَحَدِكُمْ لَوِ اتَّخَذَ ثَوْبَيْنِ لِجُمُعَتِهِ سِوَى ثَوْبَىْ مَهْنَتِهِ .
Yahya related to me from Malik from Yahya ibn Said that he had heard that the Messenger of Allah, (ﷺ), said, "There is nothing wrong in wearing two garments which are not work-clothes for jumua."
