The clause "whenever you bind yourselves by a pledge" has a twofold meaning: in the first instance (as in 13:20) it refers to the spiritual, moral and social obligations arising from one's faith in God; and, secondly, it applies to all pledges or promises given by one person to another - for, as Razi points out, every pledge given by man to man represents, in its essence, a pledge to God. It is to this second aspect of man's "bond with God" that the sequence refers.I.e., as distinct from oaths "uttered without thought" (see 2:225).Lit., "and having made God [or "named God as"] your guarantor (kafil)".
