[Machine] "He heard Abu Huraira say: 'My beloved friend advised me with three things that I will never neglect. Firstly, to never sleep except after praying Witr (an additional prayer performed after Isha prayer). Secondly, to fast three days every month. And thirdly, to never abandon the two Rak'ahs of Dhuha (a voluntary prayer performed in the morning).' "  

أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ أَوْصَانِي خَلِيلِي بِثَلَاثٍ لَسْتُ بِتَارِكِهِنَّ أَنْ لَا أَنَامَ إِلَّا عَلَى وِتْرٍ وَأَنْ أَصُومَ ثَلَاثَةَ أَيَّامٍ مِنْ كُلِّ شَهْرٍ وَأَنْ لَا أَدَعَ رَكْعَتَيِ الضُّحَى  

A similar report was narrated from Abu Hurairah, but was not attributed to the Prophet (Using translation from Nasāʾī 4360)   

عَنْ أَبِي هُرَيْرَةَ نَحْوَهُ  

[Machine] Regarding the Prophet ﷺ , he said, "Fasting on the white days is equivalent to fasting the entire year, and breaking the fast on these days is also rewarding."  

عَنِ النَّبِيِّ ﷺ قَالَ «صِيَامُ الْبِيضِ صِيَامُ الدَّهْرِ وَإِفْطَارُهُ»
