The Quran says, ‘Recite the Quran slowly and distinctly.’ (73:4) This means, read the Quran in slow, measured rhythmic tones. That is, read, paying full attention to the import of the content. When you read like this, a two-way process between Quran and its reader comes into play. For him, the Quran is an address or speech by God and his heart starts answering this address at every verse. In the Quran where there is any mention of God’s majesty, the reader’s entire existence is strongly affected by the realisation of His greatness. When God’s blessings are enumerated in the Quran, the reader’s heart overflows with gratitude; when God’s retribution is described in the Quran, the reader trembles on reading it; when an order is laid down in the Quran, the feeling becomes intensified in the reader that he should become the obedient subject of his Lord by carrying out that order.
