Dear Brothers AOA,

Now a days nasibis are doing propoganda that Our fourth Imam Zainul Abedeen(a.s) did bayat with yazeed. Further they say that he refused to take revenge from yazeed(l.a) and he wrote letter to yazeed(l.a) that he is under his bay'a and aman and He(a.s) will not participate against yazeed (l.a). I think they quote it from their books like tabari and tabaqat ibne saad. Could you shed light on this matter.
