حَدَّثَنَا مُحَمَّدُ بْنُ عُثْمَانَ الْعِجْلِيُّ، حَدَّثَنَا عُبَيْدُ اللَّهِ، - يَعْنِي ابْنَ مُوسَى - عَنْ هَارُونَ بْنِ سَلْمَانَ، عَنْ عُبَيْدِ اللَّهِ بْنِ مُسْلِمٍ الْقُرَشِيِّ، عَنْ أَبِيهِ، قَالَ سَأَلْتُ - أَوْ سُئِلَ النَّبِيُّ صلى الله عليه وسلم - عَنْ صِيَامِ الدَّهْرِ فَقَالَ ‏ "‏ إِنَّ لأَهْلِكَ عَلَيْكَ حَقًّا صُمْ رَمَضَانَ وَالَّذِي يَلِيهِ وَكُلَّ أَرْبِعَاءَ وَخَمِيسٍ فَإِذَا أَنْتَ قَدْ صُمْتَ الدَّهْرَ ‏"‏ ‏.‏ قَالَ أَبُو دَاوُدَ وَافَقَهُ زَيْدٌ الْعُكْلِيُّ وَخَالَفَهُ أَبُو نُعَيْمٍ قَالَ مُسْلِمُ بْنُ عُبَيْدِ اللَّهِ ‏.‏

I asked or someone asked the Prophet (ﷺ) about perpetual fasting. He replied: You have a duty to your family. Fast during Ramadan and the following month, and every Wednesday and Thursday. You will then have observed a perpetual fast.
