The ruling on singing if the scholars of the country permit it

If the people of a city permit something, such as the people of al-Madinah who used to permit singing, and the people of al-Kufah who used to permit nabidh, what is the ruling on singing if the scholars of the city permit it?
If we know that this scholar is criticized for singing because he sings, for example, but is upright in his condition in everything else, we investigate whether he is one of those who views singing as permissible?If it is said: Yes.
In that case, this does not disqualify him,And if it is said: No.
In that case, it does disqualify him; because he persisted in disobedience, and the scholars differ on singing, and there is no doubt in this, but Allah has placed a scale for us when scholars differ, which is the Book and the Sunnah,As Allah the Exalted said: [al-Nisa:59] , so the ruling is not weakened by the disagreement of scholars if the Sunnah is clear. What weakens the ruling is that the Sunnah is not established, or its indication of the ruling is not established; this is what weakens it. As for mere disagreement, it does not weaken the ruling, but it obligates the one deriving the ruling to investigate more so that he knows the reason for the disagreement that arose and knows the refutation of it. This is a matter that few pay attention to, as some people think that mere disagreement weakens the ruling, and this is an error,For example, if one of them says: Does camel meat invalidate the ablution or not invalidate the ablution?Then another says: Rather, it invalidates the ablution due to the hadith,The second one says: The scholars differ on it,We say: The disagreement does not harm and does not weaken the ruling as long as the evidence indicates it, and the evidence is established, and the indication is established, for then the disagreement does not weaken the ruling,But as I told you: It obligates the one deriving the ruling and looking into it to be careful and to look into why the disagreement occurred; perhaps the disagreement is for a matter he did not know, and if he knows it, he retracts his statement.
