عَنْ جُوَيْرِيَةَ بِنْتِ الْحَارِثِ رَضِيَ اللَّهُ عَنْهَا قَالَتْ أَتَى عَلَيَّ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ غُدْوَةً وَأَنَا أُسَبِّحُ ثُمَّ انْطَلَقَ لِحَاجَةٍ ثُمَّ رَجَعَ قَرِيبًا مِنْ نِصْفِ النَّهَارِ فَقَالَ مَا زِلْتِ قَاعِدَةً قُلْتُ نَعَمْ فَقَالَ أَلَا أُعَلِّمُكِ كَلِمَاتٍ لَوْ عُدِلْنَ بِهِنَّ عَدَلَتْهُنَّ أَوْ لَوْ وُزِنَّ بِهِنَّ وَزَنَتْهُنَّ يَعْنِي بِجَمِيعِ مَا سَبَّحَتْ سُبْحَانَ اللَّهِ عَدَدَ خَلْقِهِ ثَلَاثَ مَرَّاتٍ سُبْحَانَ اللَّهِ زِنَةَ عَرْشِهِ ثَلَاثَ مَرَّاتٍ سُبْحَانَ اللَّهِ رِضَا نَفْسِهِ ثَلَاثَ مَرَّاتٍ سُبْحَانَ اللَّهِ مِدَادَ كَلِمَاتِهِ ثَلَاثَ مَرَّاتٍ
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)
