Sura al-Anfāl 8:65

يَٰٓأَيُّهَا ٱلنَّبِىُّ حَرِّضِ ٱلْمُؤْمِنِينَ عَلَى ٱلْقِتَالِ إِن يَكُن مِّنكُمْ عِشْرُونَ صَٰبِرُونَ يَغْلِبُوا۟ مِا۟ئَتَيْنِ وَإِن يَكُن مِّنكُم مِّا۟ئَةٌ يَغْلِبُوٓا۟ أَلْفًا مِّنَ ٱلَّذِينَ كَفَرُوا۟ بِأَنَّهُمْ قَوْمٌ لَّا يَفْقَهُونَ

yā-ayyuhā l-nabiyyu ḥarriḍi l-muʾminīna ʿalā l-qitāli in yakun minkum ʿishrūna ṣābirūna yaghlibū miʾatayni wa-in yakun minkum miʾatun yaghlibū alfan mina lladhīna kafarū bi-annahum qawmun lā yafqahūna

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.
