Anas, from the MESSENGER OF ALLAH (SAWW) who said:
When I reached the fourth sky on the night of Me’raaj, I saw the image of ALI BIN ABI TALEB (ASWS), so I asked Jibraeel, “O Jibraeel! Is this ALI (ASWS)?”
Then I received a revelation that this was an angel that ALLAH (SWT) created in the shape of ALI BIN ABI TALEB (ASWS). Everyday seventy thousand angels come to visit this angel and praise and sanctify ALLAH (SWT). And the reward for thir praise and sanctification is written for those who love ALI BIN ABI TALEB (ASWS).
