It is narrated from Sayyida Juwayriya bint al-Harith (may Allah be pleased with her), she says: The Messenger of Allah (peace and blessings be upon him) came to me after the Fajr prayer while I was glorifying Allah Almighty, then he left for some work and returned near midday and said to me: Are you still sitting in the same state (engaged in remembrance)? I said: Yes. The Prophet (peace and blessings be upon him) said: Shall I not teach you such words that if they are weighed against all that you have recited, they will outweigh them? These words are to be said three times: Subhan Allah ‘adada khalqihi, ... to ... Subhan Allah midaada kalimatihi. (See the next hadith for the translation of these words)
