What was the criterion for recognising the hyprocrites according to Hazrat Jabir bin Abdullah Ansari (r) and other virtuous companions of Holy Prophet (saw)?
The criterion of hypocrites is disliking Imam Ali (AS) as the Prophetic Hadeeth states: No one likes Ali but a believer, and no one dislike him but a hypocrite. ( Saheeh Muslim 113) and Tirmithi 3651 and Al-Sunan Al-Suggra by al-Nasaa'ee 4978 and Sunan Ibn Maajah 111.
Soyooti narrated in his book al-Durr Al-Manthour, V.6, P.66 from Abdullah Ibn Mas'ood saying: During the time of the Messenger of Allah, we did not recognize the Munafiqs (Hypocrites) but only by their disliking Ali ibn Abi Talib.
