All the beliefs that people hold and acts of worship that they perform is called Deen, even if they are false.
Q: On the evening of Friday on the 4th of Safar 1403 A.H., I watched the TV show "The Natural World" presented by Ibrahim AlRashid. The episode was about India. While giving a quick introduction to the episode, he said that India is indeed called the land of religions where you can find Buddhism, Hinduism, Sikhism, etc. Please explain the following: Are the beliefs the presenter mentioned considered to be real faiths? Are they revealed and sent down by Allah? May Allah help you to correct any misconceptions!
A: All that people believe in and whereby perform acts of worship is called a Deen, even if it is false. Examples of these beliefs include Buddhism, Hinduism, Christianity, Judaism, paganism, and other false concepts.
"To you be your religion, and to me my religion (Islâmic Monotheism)."
Truly, the religion with Allâh is Islâm.
And whoever seeks a religion other than Islâm, it will never be accepted of him, and in the Hereafter he will be one of the losers.
This day, I have perfected your religion for you, completed My Favour upon you, and have chosen for you Islâm as your religion.
To each among you, We have prescribed a law and a clear way.
