Laymen should avoid engaging into politics:

When politics is involved, it is better to restrain your tongues, particularly when it will lead to discord:

بسم الله والحمد لله والصلاة والسلام على رسول الله ، وبعد

Narrated Abu Hurairah رضي الله عنه:

❝I have memorized two kinds of knowledge from Allaah's Messenger ﷺ. I have propagated one of them to you and if I propagated the second, then my pharynx (throat) would be cut (i.e. I would be killed).❞

📚 [Saheeh al-Bukhaaree (120)]

Shaikh Ibn al-`Uthaymeen رحمه الله said:

❝What is evident from this Hadeeth is Abu Hurairah learned two types of knowledge from the Prophet صلى الله عله وسلم. One type of knowledge is related with the Sharee`ah, which he رضي الله عنه informed, explained and propagated.

As for the second, then it was related with the Khilaafah (Caliphate). It was as if he رضي الله عنه was scared of the Fitnah (that would arise because of it) which would engulf him and others. This is why he delayed it. We do not say that he hid (the knowledge), because he did not wait till his last breath to speak about it. Rather, he had spoken about it earlier in his life, and thereafter he may have delayed speaking about it till there was no fear of the Fitnah arising because of it.❞

📚 [Sharh Saheeh al-Bukhaaree (1/319)]


🎓 In Fath al-Baaree, Ibn Hajar رحمه الله said:
❝(The knowledge which Abu Hurairah deferred from speaking about), scholars took this to refer to those Ahaadeth in which the names of the tyrant rulers, their condition, and their era are mentioned. Abu Hurairah used to refer to some of them with nicknames, and would not speak about them openly, fearing for himself. Like he used to say: “I seek Allaah’s refuge from the starting of the 60th year (of Hijrah) and the leadership of the youth”, referring  to the Khilaafah of Yazeed Ibn Mu`aawiyah, as he came to power in the 60th year of Hijrah. And Allaah تعالى accepted his Du`aa, and he died a year before (Yazeed became the ruler).❞
