The cousin of the Prophet Muhammad and his successor, Imam Ali has spoken of the lofty status of the Quran in the following manner: “And know that this Quran is an adviser who never deceives, a leader who never misleads, and a narrator who never speaks a lie. No one will sit beside this Quran but that when he rises he will achieve one addition or one diminution—addition in his guidance and elimination in his [spiritual] blindness. You should also know that no one will need anything after [guidance from] the Quran and no one will be free from want before [guidance from] the Quran. Therefore, seek cure from it for your ailments and seek its assistance in your distresses. It contains a cure for the biggest diseases, namely, unbelief, hypocrisy, revolt, and misguidance. Pray to God through it and turn to God with its love. Do not ask the people through it. There is nothing like it through which the people should turn to God, the Sublime.”
