Sūrah No. 28. Revealed in Makkah, 88 verses.
This Sūrah was revealed at a time when the Muslims faced great pressure from the enemies who were more in number and possessed worldly power. The situation was very similar to that of the Banu Israel and the people of Fir‘awn and more than half of this Sūrah narrates those stories to console and reassure the Muslims.
The Sūrah takes its name from the story Prophet Musa (a) narrated to Prophet Shu‘ayb (a) about his departure from Egypt (verse 25).
This Sūrah is the third of three Sūrahs (al-Shu‘arā’, al-Naml, and al-Qasas) that are known as the Tawāsin because of the abbreviated letters at the beginning of the Sūrahs.
