Bulugh al-Maram 689
Fasting
وَعَنْ أَبِي هُرَيْرَةَ - رضى الله عنه - عَنِ اَلنَّبِيِّ - صلى الله عليه وسلم -قَالَ: { لَا تَخْتَصُّوا لَيْلَةَ اَلْجُمُعَةِ بِقِيَامٍ مِنْ بَيْنِ اَللَّيَالِي, وَلَا تَخْتَصُّوا يَوْمَ اَلْجُمُعَةِ بِصِيَامٍ مِنْ بَيْنِ اَلْأَيَّامِ, إِلَّا أَنْ يَكُونَ فِي صَوْمٍ يَصُومُهُ أَحَدُكُمْ } رَوَاهُ مُسْلِمٌ [1] .
Abu Hurairah (RAA) narrated that The Messenger of Allah (ﷺ) said: "Do not single out Friday night (i.e. the night preceding Friday) among all the other nights for performing the night prayer. Also, do not single out Friday among other days for fasting, unless it coincides with the days one regularly fasts." Related by Muslim.
