He feared that such dissension might harm Islam and its kalima , as we have previously explained, saying that he was inflicted in those days more than anyone else by two major catastropes: On one hand, caliphate, in its texts and wills, cried unto him and invoked him in a complaint that would make the heart bleed, and the oppressive dissension on the other warned him of an uprising in the peninsula, a possible rebellion of the Arabs that would sweep Islam away, threatening it with the hypocrites among the residents of Medina who were accustomed to hypocrisy, supported by the bedouins who, according to the text of the Book of Allah (9:101), are hypocrites, nay, even worse in disbelief and hypocrisy, so much so, that it would be better for them not to know the limits of what Allah has revealed unto His Messenger (9:97).
These have become stronger by the loss of the Prophet (pbuh), peace be upon him and his progeny, and Muslims became like frightened cattle in a winter night, surrounded by assaulting jackels and wild beasts. Musaylamah the Liar, conspirator Talhah ibn Khuwaylid, and sorceress Sajah daughter of al-Harath, in addition to their rogues and hoodlums, were all trying their best to wipe Islam out and crush the Muslims.
Add to this the fact that the Romans, the followers of Kisra and Caesar, besides many others, were plotting against the Muslims. Still add to these other elements full of grudge against Muhammad, his progeny and companions, and full of hatred towards the message of Islam. All these parties desired to uproot Islam's foundations.
These were active in doing so, rushing their steps, seeing that the wind was finally blowing in their direction, and the opportunity because of the departure of the Prophet (pbuh) to the Sublime Companion had come; so, they wished to make use of that opportunity before Islam regained its strength and resumed order.
‘Ali (as) was aware of both dangers, and it was only natural that he would offer his own right on the altar of sacrifice for the sake of the Muslims.[^1] But he also wanted to maintain his right for the caliphate and argue with those who departed from it in a way that would neither harm the Muslims, nor cause dissension among them, nor encourage their enemy to take advantage thereof. He, therefore, remained at home till he felt obligated, not forced, to leave it.
