Marmaduke Pickthall, The Meaning of The Glorious Koran. An Explanatory Translation (1930)

11. There were the believers sorely tried, and shaken with a mighty shock.

12. And when the hypocrites, and those in whose hearts is a disease, were saying: Allah and His messenger promised us naught but delusion.

13. And when a party of them said: O folk of Yathrib! There is no stand (possible) for you, therefor turn back. And certain of them (even) sought permission of the Prophet, saying: Our homes lie open (to the enemy). And they lay not open. They but wished to flee.

14. If the enemy had entered from all sides and they had been exhorted to treachery, they would have committed it, and would have hesitated thereupon but little.

15. And verily they had already sworn unto Allah that they would not turn their backs (to the foe). An oath to Allah must be answered for.

16. Say: Flight will not avail you if ye flee from death or killing, and then ye dwell in comfort but a little while.

17. Say: Who is he who can preserve you from Allah if He intendeth harm for you, or intendeth mercy for you. They will not find that they have any friend or helper other than Allah.

18. Allah already knoweth those of you who hinder, and those who say unto their brethren: “Come ye hither unto us!” and they come not to the stress of battle save a little,

19. Being sparing of their help to you (believers). But when the fear cometh, then thou (Muhammad) seest them regarding thee with rolling eyes like one who fainteth unto death. Then, when the fear departeth, they scald you with sharp tongues in their greed for wealth (from the spoil). Such have not believed. Therefor Allah maketh their deeds fruitless. And that is easy for Allah.
