Al-Quran Al-Kareem
1 Reading and reflecting over the Holy Quran fulfils an Islamic duty. Thus, by reading and pondering over the Holy Quran, one fulfils an obligation and is rewarded for that. Upon fulfilling this obligation, the Holy Quran becomes a proof for him on the Day of Judgement! This takes us to the second benefit.
2 The Holy Quran will be a proof for us on the Day of Judgement. This is clear in the Hadith of Prophet Muhammad (peace be upon him): And the Holy Quran is a proof for you or against you.
