ذِكْرُ الْأَمْرِ بِالتَّسْبِيحِ وَالتَّحْمِيدِ وَالتَّهْلِيلِ وَالتَّكْبِيرِ عَدَدَ مَا خَلَقَ اللَّهُ وَمَا هُوَ خَالِقُهُ
Once Sa'd, with the Messenger of Allah ﷺ, visited a woman in front of whom were some date-stones or pebbles which she was using as a rosary to glorify Allah. He (the Prophet) said: I tell you something which would be easier (or more excellent) for you than that. He said (it consisted of saying): "Glory be to Allah" as many times as the number of that which He has created in Heaven; "Glory be to Allah" as many times as the number of that which He has created on Earth; "Glory be to Allah" as many times as the number of that which He has created between them; "Glory be to Allah" as many times as the number of that which He is creating; "Allah is most great" a similar number of times; "Praise (be to Allah)" a similar number of times; and "There is no god but Allah" a similar number of times; "There is no might and no power except in Allah" a similar number of times. (Using translation from Abū Dāʾūd 1500)
أَنَّهُ دَخَلَ مَعَ رَسُولِ اللَّهِ ﷺ عَلَى امْرَأَةٍ فِي يَدِهَا نَوًى أَوْ حَصًى تُسَبِّحُ فَقَالَ «أَلَا أُخْبِرُكِ بِمَا هُوَ أَيْسَرُ عَلَيْكِ مِنْ هَذَا وَأَفْضَلُ؟ سُبْحَانَ اللَّهِ عَدَدَ مَا خَلَقَ فِي السَّمَاءِ وَسُبْحَانَ اللَّهِ عَدَدَ مَا خَلَقَ فِي الْأَرْضِ وَسُبْحَانَ اللَّهِ عَدَدَ مَا هُوَ خَالِقٌ وَاللَّهُ أَكْبَرُ مِثْلَ ذَلِكَ وَالْحَمْدُ لِلَّهِ مِثْلَ ذَلِكَ وَلَا إِلَهَ إِلَّا اللَّهُ مِثْلَ ذَلِكَ وَلَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللَّهِ مِثْلَ ذَلِكَ»
