And We had taken from the Prophets their Covenants. And from you, and from Noah and Abraham and Moses and Jesus, son of Mary, We took from them a strong covenant.
That He may question the loyal of their loyalty and He has prepared for the disbelievers a painful torment.
O you who believe (who wish to reach Allah before death)! Remember Allah’s Blessing upon you. There had come down upon you armies. Then We sent against them a strong wind and armies that you could not see, and Allah is Ever All-Seeing of what you do.
When they came upon you from above and from below you, and when the eyes turned dull and the hearts rose up to the throats, you were harboring doubts about Allah.
There, the believers were tried and shaken with a mighty shaking.
And the disbelievers and those in whose hearts was a disease (doubt) were saying: “Allah and His Messenger did not promise us anything but pride (deception)”.
And a party of them said: “O people of Yathrib (Al-Madinah)! There is no place to stand for you (here), therefore turn back”! And (another) party of them was asking permission of the Prophet, saying: “Surely our houses are without protection”. And they were not without protection but they were just wishing to flee (from the battle).
And upon them, if an entry were made from every part of it (the city), and they had then been asked (to cause) Al-Fitnah (mischief), they would absolutely have come to it (to cause mischief) and they would not have stayed there but a little.
And certainly they had made a covenant with Allah before not to turn their backs and flee. And a covenant with Allah is a responsibility.
