Hazrat Abu Al-Aswad asked, "O Commander of the Faithful! What has become obligatory?" Hazrat Umar replied, "I have said just as the Noble Prophet (peace and blessings be upon him) said.

He (peace and blessings be upon him) said, 'Even for three.' We asked, 'If two?' He (peace and blessings be upon him) said, 'Even for two, He will admit him to Paradise.' After that, we did not ask about one."
