Riyad as-Salihin, Book 16, Hadith 1442 (In-Book) ⓘ

Sa'd bin Abu Waqqas (May Allah be pleased with him) reported: The Messenger of Allah and I went to see a woman. She had date- stones or pebbles in front of her, and she was counting and reciting Tasbih. ['Subhan-Allah' (Allah is free from imperfection)]. He said, "Shall I not inform you of what is easier or better than this for you?" You should say: 'Subhan-Allahi 'adada ma khalaqa fis-sama', wa subhan-Allahi 'adada ma khalaqa fil-ardi, wa subhan-Allahi 'adada ma baina dhalika, wa subhan-Allahi 'adada ma Huwa Khaliqun, wallahu Akbaru mithla dhalika, wal-hamdu lillahi mithla dhalika, wa la ilaha illallahu mithla dhalika, wa la hawla wa la quwwata illa billahi mithla dhalika (Subhan-Allah, equal to the number of what He created in the heaven; and Subhan-Allah, equal to the number of His creatures in the earth; and Subhan-Allah, equal to the number in between them; and Subhan-Allah equal to the number of those He will create).' Then say: 'Allahu Akbar' (Allah is Greatest) in the same way. Then say: 'Al-hamdu lillah' (praise be to Allah) in the same way. Then say: 'La ilaha illallah' (there is no true god except Allah) in the same way. Then say: 'La hawla wa la quwwata illa billah' (there is no change of a condition nor power except by Allah) in the same manner."[At-Tirmidhi].

وعن سعد بن أبي وقاص رضي الله عنه أنه دخل مع رسول الله صلى الله عليه وسلم على امرأة وبين يديها نوى -أو حصى- تسبح به فقال‏:‏ ‏"‏أخبرك بما هو أيسر عليك من هذا - أو أفضل‏"‏ فقال‏:‏ ‏"‏سبحان الله عدد ما خلق في السماء، وسبحان الله عدد ما خلق في الأرض، وسبحان الله عدد ما بين ذلك، وسبحان الله عدد ما هو خالق، والله أكبر مثل ذلك، والحمد لله مثل ذلك، ولا إله إلا الله مثل ذلك، ولا حول ولا قوة إلا بالله مثل ذلك‏"‏‏.‏ ‏(‏‏(‏رواه الترمذي وقال‏:‏ حديث حسن‏)‏‏)‏‏.‏
