al-Sajda (or Fussilat)

The Messenger of Allah (pbuh) has said, "Whoever recites it will be granted ten good deeds for each letter in it." Imam Ja'fer al-Sadiq (as) has said that it will be light for him on the Day of Judgment extended as long as his eyes can see, and a source of joy, and he will live in the life of this world praised, well-liked.
