What is the ruling on the hadith narrated that the Messenger of Allah, peace and blessings be upon him, taught a woman to glorify Allah with pebbles, a remembrance that is: "Subhan Allah (Glory be to Allah) as much as what He created in the heavens, and Subhan Allah as much as what He created on earth, and Subhan Allah as much as what is between them, and Subhan Allah as much as He is going to create; and Allahu Akbar (Allah is the Greatest) likewise; and Al-Hamdulillah (All praise is due to Allah) likewise; and La ilaha illa Allah (There is no god but Allah) likewise; and La hawla wa la quwwata illa billah (There is no might or power except with Allah) likewise"? Is its chain of narration hasan (good) or sahih (authentic), and is it permissible to act upon it and be diligent in doing so?

The chain of transmission (isnad (definition)) of the Hadith (definition) of Abu Umamah is weak due to the unknown identity (jahalah) of Khuzaimah, but it is Hasan (definition)-rare (good due to external corroboration). It has been narrated with various wordings and chains of transmission, including those reported by Ahmad, Ibn Abi Al-Dunya, Al-Nasa'i, Ibn Khuzaymah, Ibn Hibban, Al-Hakim, and authenticated by Al-Albani and others. In it, the Prophet, peace and blessings be upon him, taught Abu Umamah specific invocations (adhkar) that increase reward, such as: "Subhanallah adada ma khalaq..." (Glory be to Allah as many times as the number of what He has created...) and "Alhamdulillah adada ma khalaq..." (Praise be to Allah as many times as the number of what He has created...). Worshipping Allah through these invocations and reciting them daily is legislated, based on the Almighty's saying: "Remember Allah with frequent remembrance" (Quran 33:41) and "And the men who remember Allah often and the women who do so" (Quran 33:35), and the Prophet's saying, peace and blessings be upon him: "Let your tongue be moist with the remembrance of Allah," and Ibn Taymiyyah's statement that adherence to daily devotions (awrad) is a Sunnah (definition).
