Mukhtasar Muslim

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Whoever says these words a hundred times in a day—"(La ilaha illallah wahdahu...)" to the end—he will have a reward equal to freeing ten slaves, a hundred good deeds will be written for him, a hundred sins will be erased from him, he will be protected from Satan all day until evening, and no one will bring a deed better than this on the Day of Judgment except someone who does more than this (i.e., recites this tasbih more than a hundred times and does more good deeds). And whoever says "(Subhan Allah wa bihamdihi)" a hundred times in a day, his sins will be forgiven even if they are as much as the foam of the sea.
