Hussain, the third Imam of Shi'ism, had no possibility of freeing the Shi'ites from persecution in the ten years he was Imam during Muawiyah's caliphate, and when he rebelled during the caliphate of Yazeed he was brutally massacred along with his step-brother, from his father's side Abul Fadhle Al-Abbass(as) and all seventy of his faithfully aides and children at Karbala in Iraq..
Certain people in the Sunni world explain as pardonable the tirbitrary, unjust and irresponsible actions carried out at this time by Muawiyah, his aides and his lieutenants, some of whom were, like Muawiyah himself, among the socalled companions.
This group reasoned that according to certain Ahadeeths of The Holy Prophet(pbuh&hf)
All the companions could practice the Ijtihad, that they were excused by God
for the sins they committed, and that God was satisfied with them and forgave
them whatever wrong they might have performed.
The Shi'ites, however, do not accept this argument for two reasons:
It is not conceivable that a leader of human society like that of The Prophet Mohammad(pbuh&hf) should rise in order to revivify truth, justice and freedom and to persuade only a group of people to accept his beliefs!
A group all of whose members had sacrificed their very existence in order to accomplish this sacred end -- and then as soon as this end is accomplished give his aides and companions complete freedom to do with these sacred laws as they will.
It is not possible to believe that:
The Holy Prophet(pbuh&hf) would have forgiven the companions for whatever wrong action they might have performed. Such indifference to the type of action performed by them would have only destroyed the structure which The Holy Prophet(pbuh&hf) had built with the same means that he had used to construct it.
The Holy Prophet Mohammad Al-Mustafa(pbuh&hf) had all too many times, shown and stated that their is no room for any kind of: 'Double Standard,' philosphy in Islam let alone in his all Infallible Teaching, Character and Personality!
Those sayings which depict the companions as inviolable and pardoned in advance for every act they might perform, even one unlawful or inadmissible, are most likely apocryphal; the authenticity of many of them has not been fully established by traditional methods.
Moreover, it is known historically that the companions did not deal with one another as if they were inviolable and pardoned for all their sing and wrongdoings.
Therefore, even judging by the way the companions acted and dealt with each other, it can be concluded that such sayings cannot be literally true in the way some have understood them.
If they do contain an aspect of the truth it is in indicating the legal inviolability of the companions and the sanctification which they enjoyed generally as a group because of their proximity to The Holy Prophet(pbuh&hf).
The expression of God's satisfaction with the companions in the Holy Koran, because of the services they had rendered in obeying His Command, refers to their past actions, and to God's satisfaction with them in the past, not to whatever action each one of them might perform in the future.
