Say, “Call (Him by the name of) Allah or Ar-RaHmān, in whichever way you call, His are the Best Names.” Do not be (too) loud in your Salāh, nor be (too) low in it, and seek a way in between.
Say, “Praise belongs to Allah who has neither had a son, nor is there any partner to Him in His kingdom, nor is anyone (needed) to protect Him from (any) weakness. And proclaim His greatness, an open proclamation.
