Khasais-e-Ali - Virtues of Ali bin Abi Talib : By Al-Nisa'i

Al-Nasa'i compiled a large number of Ahadeeth in favor of Ali Ibn Abi Talib and shaped them into a book known as "Khasais Ali" or "Khasais Kubra". When the followers of Muawiyah came to know about this, they asked Al-Nasa'i to also compile the Ahadeeth in favor of Muawiyah. Al-Nasa'i rejected their will by saying that there is no Ahadeeth or saying of Prophet Muhammad in favor of Muawiyah. The Syrians then beat Al-Nasa'i till he died. A well-known Sunni scholar of Pakistan, Allamah Ghulam Rasool Saeedi also recorded this event in his famous book of Tazkiratul Mohadiseen.
