The Qur'an is Either Evidence For or Against You Seeking knowledge is obligatory on every Muslim, and the core of all knowledge is the Quran. With knowledge comes responsibility. That is why the Prophet (sas) said that "The Qur'an is either evidence for or against you.” People who recite, learn and practice the Qur'an, become the people of Quran and the Quran will be a proof for them. However, on the Day of Judgment, the Quran will stand against those who never read or practiced it in their lives.
