The Imams عليه السلام are the light of Allah, the Most Holy, the Most High

6. Ahmad ibn Idris has narrated from al-husayn ibn ‘Ubadallah from Muhammad ibn al-Hassan and Musa ibn ‘umar from al-hassan ibn Mahbub from Muhammad ibn al-Fudayl who has said that he asked abu al-Hassan عليه السلام about the meaning of the words of Allah, the Most Holy, the Most High, in the following verse of the Holy Quran. “They want to put out the light of God with their mouths, but God will certainly make His light shine forever - even though the unbelievers may dislike this.” (61:8) The Imam عليه السلام said, “They want to put out the divine authority of Amir al-Mu’minin عليه السلام with their mouths. ‘but Allah completes His light’ means the Imams عليه السلام as mentioned in, “Those who believe in him, honor and help him, and follow the light which is sent down to him, will have everlasting happiness.” (7:157) The light stands for Imam عليه السلام.”
