Importance of observing the Sunnah of Nabi (Sallallahu Alaihi Wassalam)

"Doing Qailullah (the midday nap) with the intention of observing the Sunnah of Nabi (Sallallahu Alaihi Wassalam) is better than thousands and thousands of nights that may have been spent in Tahajjud but not in accordance to the Sunnah of Nabi (Sallallahu Alaihi Wassalam)." (Hazrat Sheikh Ahmad Sarhindi R)
