"The Day He will call you" from your graves, "and you will respond with His praise." Qatadah said: meaning, with knowledge of Him and obedience to Him. The response is their emergence from their graves to the caller, the one tasked with the Trumpet. "And you will think" in the Hereafter, "that you had stayed" in the world "only a little while," as the world will seem insignificant to them.
