What is the criterion for conditions, and is judgment made based on the explicit wording, or is the condition treated according to the intention? And what is the difference between that and the rule, "Consideration is given to purposes and meanings, not to words and structures"?

The rulings regarding conditions vary depending on the type of contract or transaction, and whether it is between a person and himself, or between him and his Lord, or between him and other people. The rule "Consideration in contracts is given to intentions and meanings, not to words and structures" is correct. Intentions are known through custom, or accompanying or prior circumstantial evidence and circumstances, or through the words accompanying the contract, not merely by a bare intention. Intentions and meanings include those designated by verbal and customary evidence, and every person's speech is understood according to their language and its custom.
