Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
Once someone is consistent in praying the compulsory prayers what Sunnah prayers should they pray?
The most important Sunnah prayers are Witr and the Sunnah before Fajr. Witr is compulsory according to the Hanafi School and some of the Companions and Hanafi scholars were of the opinion that the Sunnah of Fajr is also compulsory. After that, the other Sunnah prayers before and after the compulsory prayers should be performed as well as the Duha (midmorning) prayer.
