[4:80] Whoever obeys the Messenger, verily obeys God; and whoever turns his back, We have not sent you as a watcher over them.
This verse alludes to the gathering (jamʿ) of the state of the Messenger (ṣ). He (s) said, 'Obedience to him is obedience to Us'. Whoever draws near to him draws near to Us. Those he accepts are those We accept and those he rejects are those We reject.
