to Allah’s religion and the religion of Jesus, peace be upon him. So they travelled throughout the land and adopted monasticism. They are the ones concerning whom Allah, exalted is He, said: “As for monasticism, they invented it; We did not prescribe it for them.” The Prophet, peace and blessings be upon him, then said: “Whoever believes in me, affirms me as true, and follows me has observed it as it ought to be observed; and whoever does not believe in me—they are the ones who are doomed.” (1)
It is also related from Ibn Mas‘ud, may Allah be pleased with him, that he said: I was riding behind the Prophet, peace and blessings be upon him, on a donkey, when he said to me: “O son of Umm ‘Abd, do you know how the Children of Israel came to adopt monasticism?” I said, “Allah and His Messenger know best.” He said: “After Jesus, peace be upon him, tyrants gained power over them and committed sins. The people of faith became angry and fought them, but the people of faith were defeated three times, until only a few of them remained. They said: ‘If we overcome these people, they will wipe us out, and no one will remain to call others to the religion.’ So they said: ‘Come, let us disperse throughout the land until Allah sends the Prophet whom Jesus, peace be upon him, promised to us’”—meaning Muhammad, peace and blessings be upon him. ⦗154/b⦘ They then dispersed into mountain caves and introduced monasticism.

Sa‘id ibn Jubayr narrated from Ibn ‘Abbas, may Allah be pleased with them both, that he said: There were kings after Jesus, peace be upon him, who altered the Torah and the Gospel.
