﴿ يَٰٓأَيُّهَا ٱلنَّبِىُّ حَرِّضِ ٱلْمُؤْمِنِينَ عَلَى ٱلْقِتَالِ ۚ إِن يَكُن مِّنكُمْ عِشْرُونَ صَٰبِرُونَ يَغْلِبُوا۟ مِا۟ئَتَيْنِ ۚ وَإِن يَكُن مِّنكُم مِّا۟ئَةٌۭ يَغْلِبُوٓا۟ أَلْفًۭا مِّنَ ٱلَّذِينَ كَفَرُوا۟ بِأَنَّهُمْ قَوْمٌۭ لَّا يَفْقَهُونَ ﴾

“O Prophet! Inspire the believers to conquer all fear of death when fighting, [so that,] if there be twenty of you who are patient in adversity, they might overcome two hundred; and [that,] if there be one hundred of you, they might overcome one thousand of those who are bent on denying the truth, because they are people who cannot grasp it.”

O Prophet urge on exhort the believers to fight the disbelievers. If there be twenty of you steadfast they will overcome two hundred of them. If there be read as yakun or takun a hundred of you they will overcome a thousand of those who disbelieve for they are a people who do not understand this sentence is predicative but functions as an imperative in other words let the twenty of you fight the two hundred of them and the hundred of you the thousand of them and let them stand firm against them; but when they became numerous this was abrogated by God’s saying
