The Messenger has believed in what was revealed to him from his Lord, and [so have] the believers. All of them have believed in Allāh and His angels and His books and His messengers, [saying], "We make no distinction between any of His messengers." And they say, "We hear and we obey. [We seek] Your forgiveness, our Lord, and to You is the [final] destination."
The Prophet Muhammad (peace be upon him) believes in everything that was revealed to him by his Lord, as do the believers. All of them believe in Allah, all His angels, all His books that He revealed to the various prophets and all His messengers that He sent. They believe in such messengers without making any distinction between them. They say, ‘We have heard your instructions and prohibitions, and we obey You by following Your instructions and leaving Your prohibitions. We ask You to forgive us, O Lord, for in all our matters we return to You alone’.
