Is following the opinion of some of the Salaf scholars—such as Amr ibn Dinar and Mujahid—who permitted masturbation, considered a sin?

Although there are narrations from Mujahid and others indicating the permissibility of masturbation, a Muslim should attend to what benefits and rectifies them. Avoiding this habit is better for their religion, worldly life, and mental and physical health. It causes physical exhaustion, nourishes images of the forbidden, increases lust instead of quelling it, opens doors to disobedience, and harms future marital relations. Ibn al-Arabi al-Maliki strictly prohibited it, considering it a sin introduced by Satan. He also narrated that Ibn Umar prohibited it. Some scholars have stated that the narrations permitting masturbation did not intend absolute permissibility, but rather restricted it to cases of necessity, such as fear of committing fornication or illness, as mentioned by Shaykh al-Islam Ibn Taymiyyah. These evidences indicate that the majority of scholars have affirmed the prohibition of this act and warned against its negative effects on the soul and body.
