What is the preferred action among the permissible choices for dealing with captives, and when is killing favored?

Primary text

The choice between execution, release, ransom, or enslavement is based on the perceived benefit to the Muslims; the Imam, being the most knowledgeable of the true benefit, should exercise this discretion. If the captive poses a significant threat, execution is best. If the captive is wealthy, ransom is best. If the captive's conversion is hoped for, or his assistance sought by releasing allies, release is best. If the captive's service is beneficial while his harm is mitigated, enslavement is best (as with women and children). If the Imam is undecided between the options, execution is preferred. Mujahid and Malik stated that if there are two leaders, the one who opts to execute the captives has the better opinion, and Ishaq preferred overwhelming force (*ithkhan*), unless a known captive offers the promise of obtaining many others through ransom.
