Narrated By Abu Huraira Radhiyallahu anh: My friend (the Prophet Sallallahu ailiwassalam) advised me to do three things and I shall not leave them till I die, these are: To fast three days every month, to offer the Dhuha prayer, and to offer Witr before sleeping .
- The three days are the 13th, 14th and 15th of every month of the Hijri calender.
- Dhuha prayer is the prayer to be offered after sunrise and before midday.
- Witr means "one", it is the odd raka'h that is to be offered at night. We can either pray it as 1, 3, 5, 7, 11 etc.
And Allah knows best.
