He has deeply studied the secrets of the family of Muhammad, may Allah bless him and his family. So he has discovered their secrets. Nothing has escaped him because of his outstanding qualities that his book represents clearly. Whoever considers the contents of the book carefully, namely Mu'awiya's and al Hasan's conditions, knows that they (Mu'awiya and al-Hasan were two caliphs with two different manners.
As for the manners of al-Hasan, they are the manners of the Qur'an and of the Sunnah (the Prophet's words and deeds). In other words they are the manners of the and of Imam 'Ali. As for the manners of Mu'awiya, they are the manners of the Umayyads. Namely they were the manners of Abu Sufyan and of Hind. Whoever wants to study in detail the history of the two families (the family of Muhammad and of Mu'awiya), will know their different manners.
When Islam came, Allah helped His Servant and Apostle to achieve that clear conquest and to win that glorious victory. So the Umayyad's wicked intentions disappeared. Then Abu Sufyan, his sons, and his relatives were forced to surrender in order to spare their blood. For if they had not surrendered, their blood would have been shed. So they embraced Islam as the people did, while their hearts were full of malice.
So they waited for an opportunity to carry out their wicked plans against Muhammad and his family. Though Allah's Apostle, may Allah bless him and his family, was acquainted with their attitude, he treated them kindly in order to reform them.
