Al-Anfal - 8:66

الآنَ خَفَّفَ اللّهُ عَنكُمْ وَعَلِمَ أَنَّ فِيكُمْ ضَعْفًا فَإِن يَكُن مِّنكُم مِّئَةٌ صَابِرَةٌ يَغْلِبُواْ مِئَتَيْنِ وَإِن يَكُن مِّنكُمْ أَلْفٌ يَغْلِبُواْ أَلْفَيْنِ بِإِذْنِ اللّهِ وَاللّهُ مَعَ الصَّابِرِينَ
[8:66]
For the present Allah has made light your burden, and He knows that there is weakness in you; so if there are a hundred patient ones of you they shall overcome two hundred, and if there are a thousand they shall overcome two thousand by Allah's permission, and Allah is with the patient.
For the present, Allah hath lightened your (task), for He knoweth that there is a weak spot in you: But (even so), if there are a hundred of you, patient and persevering, they will vanquish two hundred, and if a thousand, they will vanquish two thousand, with the leave of Allah: for Allah is with those who patiently persevere.
Now hath Allah lightened your burden, for He knoweth that there is weakness in you. So if there be of you a steadfast hundred they shall overcome two hundred, and if there be of you a thousand (steadfast) they shall overcome two thousand by permission of Allah. Allah is with the steadfast.
