The most honored salawat which awliyaullah said one recitation equals 70,000 salawat, and in the Shafi`i school of thought they say it is “rewarded with no end,” as Allah's Perfection has no end! It is read between Maghrib and `Isha, especially to remove forgetfulness and strengthen the memory:
O Allah! Grant salawat on the Prophet without end on the number of perfection with which You dressed him!
