Zayd bin Ali bin Al-Husayn (P) said about this sect...
Zayd bin Ali bin Al-Husayn (P) said about this sect: "Owing to the propaganda of these people with the hope that Allah will forgive sins, the sinners have become encouraged to commit any sin they like." This was the belief of Murjia' at that time and the belief of the Shi'ah was its opposite. However, nowadays the Shi'ah say what Murjia' used to say in olden times.
At that time the belief of the Shi'ah was in accordance with this Qur'anic text: "Faith is necessary and good deeds are also necessary. " The third explanation is that the circumstances had taken such a turn in the world of Islam that Imam Husayn (P) considered it his duty to rise. He was of the view that it was necessary for him, rather it was his duty to rise for the safety of Islam.
His difference and dispute with the caliph of the time was not as to who from between them should be the Caliph and whether the Holy Imam was entitled to hold the office which was held by Yazid. Their difference was basic and fundamental. If instead of Yazid another person had done the same deeds and adopted the same ways and manners, Imam Husayn (P) would have risen against him as he rose against Yazid whether the treatment meted out by him to the Holy Imam himself had been good or bad.
Yazid and his supporters were prepared to render every assistance to Imam Husayn (P) provided that he did not interfere with what they did and confirmed their conduct. If the Holy Imam had asked for a territory e.g. if he had demanded that the rulership of the Hijaz and Yemen might be given to him or the administration of the provinces of Iraq and Khorasan might be placed at his disposal they would certainly have entrusted these territories to him.
He would also have been given full control on these territories. He might have collected as much revenue as he liked and might have spent it ill the way he wished. It would have been at his discretion to send any money to the central government or not. In fact the battle of Imam Husayn (P) was the battle of principle and faith. It was the battle between truth and falsehood.
And in this battle of truth and falsehood the position of Imam Husayn's (P) own person was secondary .He had made this thing clear to his companions in a few words. He uttered these words in a sermon which was most probably delivered when Hur and his companions had arrived and on this account it was a general address. He said: "Don't you see that truth is not being followed and false-hood is not being avoided.
