It is narrated from Hazrat Mu'adh (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: "For the person in whose favor three people bear witness, Paradise becomes obligatory for him." Hazrat Mu'adh (may Allah be pleased with him) asked, "O Messenger of Allah! What if there are two?" He replied, "If there are two, then the same ruling applies."
