Surah Al-Ahzab Ayahs #15 Translated in English

There the believers were tested and shaken with a severe shaking.

And [remember] when the hypocrites and those in whose hearts is disease said, "Allāh and His Messenger did not promise us except delusion,"

And when a faction of them said, "O people of Yathrib, there is no stability for you [here], so return [home]." And a party of them asked permission of the Prophet, saying, "Indeed, our houses are exposed [i.e., unprotected]," while they were not exposed. They did not intend except to flee.

And if they had been entered upon from all its [surrounding] regions and fitnah [i.e., disbelief] had been demanded of them, they would have done it and not hesitated over it except briefly.

And they had already promised Allāh before not to turn their backs [i.e., flee]. And ever is the promise to Allāh [that about which one will be] questioned.
