Which is more correct when rising from bowing in prayer: "Rabbana wa laka al-hamd hamdan katheeran tayyiban mubarakan feeh" (Our Lord, and to You be praise, much good blessed praise in it) or "Rabbana laka al-hamd hamdan katheeran tayyiban mubarakan feeh" (Our Lord, to You be praise, much good blessed praise in it)? And should "katheeran" (much) be said before "tayyiban" (good) or the reverse? What is the ruling on the prayer of one who reverses them?

There are four forms of praising Allah during prayer: "Rabbana laka al-hamd" (Our Lord, to You be all praise), "Rabbana wa laka al-hamd" (Our Lord, and to You be all praise), "Allahumma Rabbana laka al-hamd" (O Allah, our Lord, to You be all praise), and "Allahumma Rabbana wa laka al-hamd" (O Allah, our Lord, and to You be all praise). All of them are permissible, and scholars differed on which is best. Malik and Ahmad preferred "Rabbana wa laka al-hamd", while Ath-Thawri and the Kufans preferred "Rabbana laka al-hamd". As for the supplication "Rabbana wa laka al-hamd, hamdan katheeran tayyiban mubarakan feeh" (Our Lord, and to You be all praise, abundant, good, blessed praise), Ahmad narrated it without the conjunction "wa" (and), while Al-Bukhari narrated it with it. It is permissible for the worshipper to prioritize either of the two phrasings over the other.
