The Muslims would not have been divided and in disagreement had it not been for the , for every disagreement that has been created in the past, or is being created at the present time is due to their disagreement about the .
There is one God, one Qur'an, one Messenger and one Qiblah, and they all agree on that, but the disagreement among the started on the first day after the death of the Messenger (saw), in the Saqifah (house) of Bani Saidah, and has continued up to the present day, and will continue for as long as Allah wills it.
Through my discussions with the Shiite scholars, I discovered that, in their views, the were divided into three categories: The first category included the good who knew Allah and His Messenger truly well, and they acclaimed him (the Messenger) to the last moments of their lives. They were truly his friends by words and deeds, and they never abandoned him, but rather stood their ground with him.
Allah - the most High - praised them in many places in His Holy Book, and the Messenger of Allah (saw) also praised them in many places. This group of are mentioned by the Shi’a with reverence and respect, they are also mentioned by the Sunnis with the same reverence and respect. The second category were the who embraced Islam and followed the Messenger of Allah (saw) either through choice or through fear, and they always showed their gratitude to the Messenger of Allah (saw) for their Islam.
However, they hurt the Messenger of Allah (saw) on a few occasions, and did not always follow his orders, in fact they often challenged him and challenged the clear text with their points of view, until Allah, through the Holy Qur'an, had to intervene by rebuking them or threatening them. Allah exposed them in many Qur'anic verses, also the Messenger of Allah (saw) warned them in many of his sayings. The Shi’a mention this group of only because of their deeds, and without respect or reverence.
The third type of were the hypocrites who accompanied the Messenger of Allah (saw) to deceive him. They pretended to be Muslims but inside themselves they were bent on blasphemy and on deceiving Islam and the Muslims as a whole. Allah has revealed a complete Surah in the Qur'an about them, and mentioned them in many other places, and promised them the lowest level in Hell.
Also the Messenger of Allah (saw) mentioned them and issued warnings about them, and even informed some of his close friends about their names and characteristics.
