Samura b. Jundub reported God's messenger as saying, "The most excellent words are four:Glory be to God; Praise be to God; there is no god but God; and God is most great." A version has, "The words dearest to God are four: Glory be to God; Praise be to God; there is no god but God; and God is most great. It does not matter which you say first." Muslim transmitted it.
