Al-Anfal - 8:65

يَا أَيُّهَا النَّبِيُّ حَرِّضِ الْمُؤْمِنِينَ عَلَى الْقِتَالِ إِن يَكُن مِّنكُمْ عِشْرُونَ صَابِرُونَ يَغْلِبُواْ مِئَتَيْنِ وَإِن يَكُن مِّنكُم مِّئَةٌ يَغْلِبُواْ أَلْفًا مِّنَ الَّذِينَ كَفَرُواْ بِأَنَّهُمْ قَوْمٌ لاَّ يَفْقَهُونَ
[8:65]
O Prophet! urge the believers to war; if there are twenty patient ones of you they shall overcome two hundred, and if there are a hundred of you they shall overcome a thousand of those who disbelieve, because they are a people who do not understand.
O Prophet! rouse the Believers to the fight. If there are twenty amongst you, patient and persevering, they will vanquish two hundred: if a hundred, they will vanquish a thousand of the Unbelievers: for these are a people without understanding.
O Prophet! Exhort the believers to fight. If there be of you twenty steadfast they shall overcome two hundred, and if there be of you a hundred (steadfast) they shall overcome a thousand of those who disbelieve, because they (the disbelievers) are a folk without intelligence.
