One of the most majestic statements in the Qur'an. The Word of Allah is tammat — completed, perfected — along two axes: ṣidqan (in truthfulness, as report and information) and 'adlan (in justice, as command and law). Whatever the Qur'an says is true; whatever it commands is just. Maududi emphasizes the consequence: lā mubaddila li-kalimātih — no one can replace or alter His words. Throughout history, distorters have tried; every attempt has failed. The Qur'an stands today as it was revealed, and Allah Himself remains al-Samī' al-'Alīm, hearing every word said against it and knowing every plot to subvert it.
