The MESSENGER OF ALLAH (SWT) said:
“Should I guide you to someone who will not lead you astray and who will prevent you from being destroyed if you follow him?”
People said, “Yes, O MESSENGER OF ALLAH (SWT)!”
The PROPHET (SAWW) said, “Your Imam and your Wali is ALI BIN ABI TALEB (ASWS). So support him, follow his advice, and believe in him. Jibraeel ordered me to tell you this.
