DARIMI 1786:
from Aṣūm Thalāthah Ayyām from Kul Shahr —
[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).' "

عن اصوم ثلاثه ايام عن كل شهر —
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
