Hazrat Muslim bin Abi Maryam narrates that Hazrat Umm Hani came to the service of the Noble Prophet (peace and blessings be upon him) and said: O Messenger of Allah (peace and blessings be upon him)! I have reached old age and have become weak. Please teach me a deed that I can continue to do while sitting. The Messenger of Allah (peace and blessings be upon him) said: If you declare the greatness of Allah a hundred times, it is better than a hundred accepted camels adorned with bridles; and indeed, if you declare the purity of Allah a hundred times, it is better than a hundred slaves whom you have set free; and indeed, if you praise and glorify Allah a hundred times, it is better than a hundred horses saddled and bridled, upon which goods are tied to be sent in the way of Allah.
