What is the response to those who consider singing and musical instruments permissible?

Question:
One of the researchers conducted a study on singing and musical instruments, and said: My opinion has settled on the permissibility of all of that. What is your opinion, Your Eminence?

Answer:
This requires a detailed explanation:
As for the well-known Arabic poetry, there is nothing wrong with it if its meaning is calling to Allah, or encouraging generosity, kindness, and good deeds, or jihad, or mocking the enemies, or urging jihad, or the like, as Hassan, Ka'b ibn Malik, Abdullah ibn Rawahah, and others used to do. This is an accepted matter. Likewise, the chant that supports the truth, as the Prophet (peace and blessings be upon him) and the Companions did when they were digging the trench, and when building his (peace and blessings be upon him) mosque:
O Allah, had it not been for You, we would not have found guidance
We did not give charity, nor did we pray,
So send down upon us tranquility,
And make firm our feet if we meet [the enemy].

All of this is good.
As for the instruments of amusement, or the well-known singing that resembles the singing of women with their coquetry and the melodies of women; this is forbidden according to the majority of the scholars. A few went to the permissibility of a small amount of it, but the majority of the scholars are on its absolute prohibition. And if it calls to intoxicants, unlawful sexual intercourse, or obscenities, it is forbidden by consensus. But if its form calls to the desire for women and to sins, that is forbidden. And if it is with the voices of women, that is forbidden; because Allah said: [Al-Ahzab: 32], so it is forbidden for men to listen to it. As for among themselves, there is nothing wrong with it. Among women at a wedding, there is nothing wrong with it, as came from the Prophet (peace and blessings be upon him), with the hand drum, or the maids on the days of the festival with poems that have no harm in them, as the Prophet (peace and blessings be upon him) approved the two maids reciting poetry in the house of A'ishah, with the poems of the Ansar on the day of Bu'ath on a day of festival, and he said: , and he ordered the Caliph, saying: , there is nothing wrong with this.
And Ibn al-Salah said: The scholars agreed that singing with some instruments of amusement is forbidden by consensus. The disagreement is only if it is singing alone, with nothing else. The majority are on its absolute prohibition: the singing that comes from women, or from men in the manner of women. As for Arabic poetry in the language of the Arabs and the melodies of the Arabs, this is permissible with no disagreement. Hassan did it in the presence of the Prophet (peace and blessings be upon him), and Ka'b ibn Malik did it, and Abdullah ibn Rawahah did it. Likewise, the good chant that calls to good among men, as they did on the day of the trench, and as they did in building the mosque of the Prophet (peace and blessings be upon him). It is not permissible to mix and confuse [the issues].
As for the instruments of amusement, they are all forbidden: the oud, the violin, the music, the drum. The instruments of amusement have no detail [in their ruling]; they are all denounced. We have written a separate treatise on this, for a long time, which is distributed. We clarified the evidence in it in detail, so we hope it will be published soon in the newspapers for the sake of broadening the benefit. And it will be printed and distributed, if Allah wills. It has been printed many times and distributed many times, but the need is pressing now to distribute it in every place.
