Tafsir of Ash-Shu`ara' 26:220

Verily, He, only He, is the All-Hearer, the All-Knower. He hears all that His servants say and He knows all their movements, as He says:

وما تكون فى شٲن وما تتلوا منه من قرءان وﻻ تعملون من عمل إﻻ كنا عليكم شهودا إذ تفيضون فيه

Neither you do any deed nor recite any portion of the Qur'an, nor you do any deed, but We are Witness thereof, when you are doing it. (10:61)
