“If there are twenty steadfast among you, they will overcome two hundred” (al-Anfāl 8:65) is followed by an explicit easing in 8:66: “Now Allah has lightened [the burden] for you.”
This case differs from a merely lexical problem. The later verse expressly addresses a changed measure of obligation, so interpreters must assess the relation between an earlier practical standard and its subsequent reduction.
Even here, courage as a virtue and a legally enforceable ratio are not identical. The explicit language of easing is important evidence, but the precise legal implication should be stated with care.
