﴿ ٱلْـَٰٔنَ خَفَّفَ ٱللَّهُ عَنكُمْ وَعَلِمَ أَنَّ فِيكُمْ ضَعْفًۭا ۚ فَإِن يَكُن مِّنكُم مِّا۟ئَةٌۭ صَابِرَةٌۭ يَغْلِبُوا۟ مِا۟ئَتَيْنِ ۚ وَإِن يَكُن مِّنكُمْ أَلْفٌۭ يَغْلِبُوٓا۟ أَلْفَيْنِ بِإِذْنِ ٱللَّهِ ۗ وَٱللَّهُ مَعَ ٱلصَّٰبِرِينَ ﴾
“For the time being, [however,] God has lightened your burden. for He knows that you are weak: and so, if there be one hundred of you who are patient in adversity, they should [be able to]' overcome two hundred; and if there be one thousand of you, they should [be able to] overcome two thousand by God's leave: for God is with those who are patient in adversity.”
(Now hath Allah lightened your burden, for He knoweth that there is weakness in you) in relation to fighting. (So if there be of you a steadfast hundred) who seek their reward only from Allah (they shall overcome) they shall fight (two hundred, and if there be of you a thousand (steadfast) they shall overcome) they shall fight (two thousand by permission of Allah. Allah is with the steadfast) He helps the steadfast in war by making them triumphant.
