It is narrated from Sayyidah Umm Hani' (may Allah be pleased with her): The Prophet (peace and blessings be upon him) came to me and I said: "O Prophet of Allah, teach me a deed that I can do while sitting, for standing has now become hard for me." He (peace and blessings be upon him) said: "O Umm Hani'!" I said: "Here I am, O Prophet of Allah!" He (peace and blessings be upon him) said: "Say Subhanallah (Glory be to Allah) one hundred times, for it is equal to freeing one hundred slaves; say Alhamdulillah (All praise is for Allah) one hundred times, for it is equal to (giving) one hundred horses with their equipment (for riding) in the path of Allah; say Allahu akbar (Allah is the Greatest) one hundred times, for it is equal to sacrificing one hundred camels covered with saddle-cloths and dedicated (to the path of Allah); and say La ilaha illallah (There is no god but Allah) one hundred times, for it does not pass over any sin without erasing it."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Salim al-Bunani (may Allah have mercy on him) except Juwayriyah bin Muhammad, and he is Juwayriyah bin Bashir; Musa bin Isma'il is alone in narrating it."
