What is the authenticity, explanation, and application of the Hadith: "If you see scholars at the doors of rulers, then accuse them"?

There is no authentic Hadith with the wording: "Scholars are the trustees of the Messengers, unless they incline towards rulers." However, it was reported from Ja'far al-Sadiq that he said: "Scholars are the trustees of the Messengers. So, if you see scholars inclining towards rulers, then accuse them."

Among the authentic Marfu‘ (traced back to the Prophet) Hadiths in this regard are: 1. The Prophet, peace and blessings be upon him, said: "Beware of the doors of the ruler, for it has become difficult to descend," meaning it is humiliating and disheartening for one's work and status. 2. He, peace and blessings be upon him, said: "Whoever comes to the doors of the ruler will be tempted," meaning he will fall into tribulation, either by risking his religion through agreeing with their actions or his worldly life through opposing them.

This only applies if one regularly associates with them out of desire for their worldly gains, or if one flatters and dissimulates by remaining silent about the truth. However, whoever proclaims the truth and fears not the blame of any blamer for the sake of Allah is among the Mujahideen, as the Prophet, peace and blessings be upon him, said: "Indeed, one of the greatest forms of Jihad is a word of justice spoken to a tyrannical ruler."

Among the sayings of the Companions in this regard are: Ali ibn Abi Talib: "Beware of the doors of the ruler." Ibn Mas'ud: "Indeed, at the doors of the ruler are temptations like the rubbing places of camels. You will not gain anything from their worldly possessions except that they will take the like of it from your religion."
