Tafsir of As-Saffat 37:172

And, verily, Our Word has gone forth of old for Our servants, the Messengers, that they verily would be made triumphant, meaning, `in this world and in the Hereafter, as We have already stated that they would prevail over their people who disbelieved in them and went against them, and how Allah destroyed the disbelievers and saved His believing servants.
