What is the preponderant opinion regarding whether cupping invalidates the fast?

Cupping (Hijama) is the incision or wounding of an organ and the suction of blood from it for the purpose of healing. It is recommended due to the Prophet’s (peace be upon him) saying: "If there is any good in your remedies, it is in the scarification of a cupper." Scholars differed on the ruling of cupping for a fasting person. The three Imams (Abu Hanifa, Malik, and Al-Shafi'i) held that it does not break the fast, citing the Hadith of Ibn Abbas that the Prophet underwent cupping while fasting. However, Imam Ahmad held that it does break the fast based on the Hadith: "The one who cups and the one who is cupped have broken their fast." The more preponderant opinion is that it does not break the fast, and that the Hadith about breaking the fast is abrogated, or that it means they caused themselves to break the fast. It is better for someone who would be weakened by cupping to delay it until night, for fear of being forced to break the fast.
