What should I do about my uncle's refusal to postpone the consummation of my marriage to my wife, whom I have already contracted marriage with, and his insistence on immediate marriage or divorce, given that I am not financially ready and am committed to her?

One spouse must respond to the other's request to postpone the consummation, and this is referred back to custom, such as two or three days, seeking ease and simplicity. Neither spouse should be given an extension for preparing a trousseau if requested by the other.

Therefore, your uncle is not obligated to wait for you for a period longer than what is customary. Try to persuade him to complete the marriage with the easiest possible expenses or to give you another extension. Otherwise, he would have the right to request a divorce.
