It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, Allah Almighty has one hundred mercies. He distributed one mercy among the people of this world, which suffices them until the end of their lives, and He has kept ninety-nine mercies in reserve (in the Hereafter) for His friends (awliya'). And on the Day of Resurrection Allah Almighty will join even that one mercy, which He had distributed among the people of this world, to those ninety-nine, so as to complete one hundred mercies for His friends." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it with this wording.
