It is narrated from Sayyidah Umm Hani' bint Abi Talib (may Allah be pleased with her) that she said to the Prophet (peace and blessings be upon him): "I have grown old and weak, so tell me of a deed that I can do while sitting." He (peace and blessings be upon him) said: "If you proclaim the greatness of Allah a hundred times (say Allahu Akbar), it is better for you than a hundred sacrificial camels draped in cloth and accepted; if you glorify Him (say Subhan Allah) a hundred times, it is better for you than freeing a hundred slaves; if you praise Allah (say al-Hamdu lillah) a hundred times, it is better for you than a hundred horses, saddled and bridled, on which you mount (fighters) in the path of Allah; and if you declare His oneness (say La ilaha illa Allah) a hundred times, no deed can surpass it, and no sin remains while it is there."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Muhammad bin Ajlan except Hatim."
