Al Hamd li Allah (Praise be to Allah), this Revised Edition is a culmination of experiences in the last two decades of publishing translations of the meaning of Qur'an in several languages. With the Grace of Allah, amana publications, a subsidiary of Amana Corporation has succeeded in publishing this great work of the late 'Abdullah Yusuf 'Ali, revised for the first time after his death with the highest standard of scholarship and authenticity that it deserves. About eight years ago, the work for this edition began when we started the selection of the most recognized and authentic available English translation of the meaning of the Qur'an. The selection committee, comprised of highly reputable Muslim scholars, decided on the work of 'Abdullah Yusuf 'Ali and solicited opinions and criticisms from Islamic institutions and scholars around the world. A number of committees reviewed all the responses carefully, examined the text meticulously, updated the material and refined the commentaries. The last complete review was undertaken by the late Ismail Raji al Faruqi, who was then President of the International Institute of Islamic Thought (IIIT) in the United States of America. Guided by its own commitment to serve the Qur'an, amana publications undertook this tremendous task, and in cooperation with the IIIT completed this honorable work. amana publications and IIIT established an editorial board whose effort was to implement the final recommendations of the committees and to concentrate on the manuscript preparation, overall editorial changes, and revisions in style and format (discussed in the Preface to the Revised Edition). All praise be to Allah for enabling us to serve the Qur'an by making available this Revised Edition. We acknowledge with deep appreciation the efforts of IIIT and all those who helped produce this monumental work of 'Abdullah Yusuf 'Ali. May Allah bless his soul and reward him generously; wa al Hamd li Allah Rabb al 'Alamin (All Praise and Gratitude is due to Allah, the Lord and Sustainer of the Worlds).
