Jabir ibn Abdullah reported: A man asked the Messenger of Allah and he said, “O Messenger of Allah, do you think if I pray the five prescribed prayers, I fast the month of Ramadan, and I uphold what is lawful and unlawful without adding anything to it, will I enter Paradise?” The Prophet, peace and blessings be upon him, said:

Yes.
