What is the ruling on one who said that he entered a Buddhist temple in India and learned from them forgiveness and pardon, and claimed that he had a teacher from among them, and that Buddhism is a philosophy of life and not a religion?

Everything people profess and worship is called a religion. However, the true religion is Islam alone. Allah says: "And whoever desires a religion other than Islam, it will never be accepted from him, and in the Hereafter he will be among the losers." Islam is a complete religion in its doctrines, dealings, acts of worship, and morals. There is no deficiency in it that would necessitate searching for good morals outside of it. It is not permissible for a Muslim to take a pagan teacher whom he loves and whose guidance he follows, nor to enter the temples of disbelievers except for a legitimate, recognized Sharia purpose, such as inviting them to monotheism. The Prophet, peace and blessings be upon him, became angry with those who wanted to learn from the books of the People of the Book, so how about those who wish to learn from pagans and glorify them? Islam is the religion that brought noble morals. The Prophet, peace and blessings be upon him, said: "Indeed, I was sent to perfect noble morals." It calls for forgiveness, pardon, and suppressing anger, as in His saying, the Almighty: "and those who suppress anger and pardon people - and Allah loves the doers of good."
