4820 When once the fight (Jihad) is entered upon, carry it out with the utmost vigour, and strike home your blows at the most vital points (smite at their necks), both literally and figuratively. You cannot wage war with kid gloves.
4821 In the first onset there must necessarily be great lass of life; but when the enemy is fairly beaten, which means, in a Jihad, that he is not likely to seek again the persecution of Truth, firm arrangements should be made to bring him under control. I thus construe the words "bind a bond firmly (on them)", but others have construed the words to mean, "after the enemy's numbers are fairly thinned down, prisoners may be taken". With this passage may be compared 8:67, and n. 1234.
4822 When once the enemy is brought under control, generosity (i.e., the release of prisoners without ransom) or ransom is recommended.
4823 The Believers are tested in Faith by the extent to which they are willing to make sacrifices, even to the laying down of their lives; and the enemies are tested as to whether they would repent and let the righteous live in freedom and security.
4824 There are two alternative readings. (1) qatalu, "those who fight", and (2) qatilu, "those who are slain". The meaning under the first reading is wider, and includes that under the second. I have translated on the basis of the second reading, which is in accordance with the text of the Royal Egyptian edition
1 Another possible interpretation: “And those who fight in the cause of Allah.”
