One day, with the simple pages of the book of Sufism and Mullah, she will bring shame to the gates of Judgment.

This profound couplet by Allama Iqbal is a critique of outward religious ritualism versus inner spiritual truth. The 'Mullah's book' represents the rigid dogma and scholarly rules, while the 'Sufi's book' symbolizes the raw, experiential truth of the heart. The poet predicts that on the Day of Judgment, this simple book of Sufi wisdom will expose the superficiality and hypocrisy of those who merely follow rigid doctrines without genuine spiritual understanding.
