Question:
What is more virtuous: more Tawaaf, more Nafl Salah or more Umrah?
Answer:
The Nafl Tawaaf is more virtuous than the Nafl Salah for an outsider (a non resident of Makkah), and Nafl Salah is more virtuous than the Nafl Tawaaf for a resident of Makkah. The Nafl Tawaaf is more virtuous than Nafl Umrah as long as the time spent for both is the same.
