But according to the majority of Ahle Sunnat, all the companions were just and thus all the traditions reported by them are authentic and reliable. However, according to Shia scholars, all the companions were not just that traditions reported by them couldn't be accepted without scrutiny. Yes! Even though the differences are minute, they are very important because the traditions of the Holy Prophet (s.a.) have reached us only through the companions.
Hence the justice of companions is an important criterion for the correctness of the narrations. The humble writer of this book was a common Sunni scholar. In spite of this he always maintained that all the companions of the holy Prophet (s.a.w.a.) were not just. This can be illustrated as follows: The Ahle Sunnat accept the narrations of the companion Mughirah bin Shu'bah and also consider him to be just. But it should be known that justice has no existence outside a person.
It is apparent through the actions of that person. But if someone opposes the established commands of Islam, whoever it may be, far from his being just, he would be labeled a sinner and unjust person. This is established through the opinions of well-known Ahle Sunnat scholars. Please note the factors that show whether Mughirah was a sinner or a just person. History chronicles that Mughirah was the governor of Basrah during the Caliphate of second caliph.
In this period, he committed fornication with a woman named Umme Jamil of the Bani Aamir tribe. Four companions witnessed this act. One was Abu Bakr and others were Nafe, Shabil and Ziyad. In the beginning three of them testified. The fourth one gave a false testimony and thus saved him from the punishment of stoning. It is clear that Mughirah had committed fornication and became eligible for a verdict of stoning from the Caliph.
The complete incident is recorded in various history books, especially the book, Fitratul Islam. Ibne Abil Hadeed has also considered as insufficient the testimony of people who committed greater sins and did not consider their hadith reliable. Mughirah was the ruler of Kufa when he saw Amirul Momineen (a.s.) and (God forbid) uttered a curse on him.
So much so that the writer of Fitratul Islam and Ibne Abil Hadeed, the Shafei scholar, says that Mughirah bin Shu'bah cursed Ali (a.s.) and his pure descendants in the presence of Saeed bin Zaid, the great companion. Many other companions who left the Masjid in disgust also witnessed this.
