وَقَالَ يَحْيَى : سَمِعْتُ مَالِكًا ، يَقُولُ : لَمْ أَسْمَعْ أَحَدًا مِنْ أَهْلِ الْعِلْمِ وَالْفِقْهِ وَمَنْ يُقْتَدَى بِهِ يَنْهَى عَنْ صِيَامِ يَوْمِ الْجُمُعَةِ ، وَصِيَامُهُ حَسَنٌ وَقَدْ رَأَيْتُ بَعْضَ أَهْلِ الْعِلْمِ يَصُومُهُ وَأُرَاهُ كَانَ يَتَحَرَّاهُ
Imam Malik, may Allah have mercy on him, said: I have not seen any scholar who forbids fasting on the day of Jumu'ah, rather fasting on the day of Jumu'ah is better, and I have seen some people of knowledge fasting on the day of Jumu'ah, in fact, I have seen that they would pay special attention to Jumu'ah for the sake of fasting.
