Translation:

5. "Our Lord! Make us not a (test and) trial for the Unbelievers but forgive us our Lord! For Thou art the Exalted in Might the Wise."

Notes (Tafseer)

5417. In n. 1198 to viii. 25, I have explained the shades of meaning in the word Fitnat. In ii. 102 Harut and Marut were a trial to test the righteous who trusted in Allah from the unrighteous who resorted to evil and superstition. Here the prayer to Allah is that we should be saved from becoming so weak as to tempt the Unbelievers to try to attack and destroy us.
