If a suitor proposes to a girl who is the eldest and has not yet been proposed to, they delay the marriage of the younger one. Perhaps you are seeking a solution for this?

Question:
Some communities, Shaykh Salih, still adhere to customs and traditions like this one. If a suitor proposes to one of the daughters, and the younger one is chosen while an older sister has not yet been proposed to, they obstruct the marriage of the younger one for the sake of the older one. These are customs, Shaykh Salih. Perhaps you can find a solution for them. May Allah reward you with good.

Answer:
There is no doubt that if people were left to their own devices regarding this custom, it would die out and be forgotten, and the concern for which they adhered to it would be removed. We hope for that. In any case, regarding matters that people have become accustomed to but which have no basis in the Shari'ah, it is obligatory to abandon them, to consider the benefits and opportunities before they are lost, and to leave behind customs that cause harm to some people without sin or reason. Submitting to customs, especially when they are harmful, involves harms. As for good customs that do not conflict with the rules of the Shari'ah, there is nothing wrong with adhering to them. Yes.
