Shaykh Salih al-Fawzaan said:

It is obligatory to respect the Scholars of the Muslims because they are the Inheritors of the Prophets. Belittlement of them is considered belittlement of their standing and their inheritance from the Prophet (sallallaahu alayhi wasallam) and belittlement of the knowledge that they carry.

And whoever belittled the Scholars will certainly (find it easy) to belittle others amongst the Muslims. It is obligatory to respect the scholars due to their knowledge and their standing in the ummah, and due to the responsibility that they take over for the benefit of Islam and the Muslims. And when there is no trust in the Scholars, then whom shall they trust? When the trust in the Scholars has been wasted then who shall the Muslims turn to to solve their difficulties and to explain the rulings of the Shari'ah? Then the ummah will be wasted (ruined) and confusion will spread. When the scholars strives and is correct, he has two rewards, and when he strives and errs then he has one reward. And the mistake is forgiven. There is no one who belittled the Scholars except that he subjected himself to punishment. And history is the best witness for that, (both) in the distant past and the present (modern) era.

From al-Ajwibah al-Mufeedah of the Shaykh as cited on page 7 of the book, "They Turned Dammaaj Into a Torch of Fire After It Was a Torch of Light" (read here).

Read that again: "There is no one who belittled the Scholars except that he subjected himself to punishment. And history is the best witness for that, (both) in the distant past and the present (modern) era." And then take an admonition from the observations of Shaykh Muhammad bin Abdul-Wahhab al-Wasaabee (see here), who is the senior-most of the students of Shaykh Muqbil:

O Allah bear witness, we do not wish that the mistake of Dammaaj should be repeated. They made it a torch of fire after it was a torch of light. They changed it into a torch of fire after it was a torch of light. The recompense for an action is of its like, and as you behave and deal (with others), then likewise it will be done to you. Look at Shaykh Abdur-Rahmaan [whom the Hajaawirah attacked and made tabdee' of], he was patient, he did not speak, and he just continued on, he bore their harm... and some of them were saying that they have been making du'a against him since 1428H. But look what happened, they got overturned on their heads, and their du'a in fact fell upon themselves. They made du'a against a Sunni Shaykh who calls to Tawheed and Sunnah and to the aqeedah and to fiqh, a Sunni Shaykh! It did not harm him alhamdulillaah, but it harmed you and whoever is upon your way. It is as if you O fulaan, when you make du'a, then the angels say "and the same to you", every time you made du'a [against Shaykh Abdur-Rahman) the Angels said "and the same to you" and it did return upon you and from Allaah is aid sought.

Brothers, take lesson from Dammaaj, the mother of all centers (umm al-maraakiz), how it used to be in the life of Shaykh Muqbil (rahimahullaah), it was a torch of light. There was love, affection, respect, mercy, knowledge, action, teaching, da'wah to Allaah and so on. Then when came al-Hajuri, what did he do? He destroyed it. He demolished it. Dammaaj did not fall at the hands of the Houthis, they only came afterwards. They came after al-Hajuri came and destroyed Dammaaj. Revilements, abuse, cursing, cutting off, turning backs on each other, revilements upon scholars, cursing, giving fatwas without evidences. The Houthis only came afterwards when Dammaaj was already destroyed by al-Hajuri

The maraakiz are many and the duroos are many, so there is abundance so fear Allaah and keep away from qeel and qaal (i.e. speaking about other maraakiz and students and scholars), speaking about the Shaykh of markaz and speaking about this and that. This is what destroyed Dammaaj. "Allaah does not change the condition of a people until they change what is with themselves" (13:11). The verse contains the precursor (muqaddimah) and the end-result (khaatimah). When they change what is with themselves, the situation will be made to change over them. When they change then the end-result will come to them. There is no doubt that Dammaaj has been changed, but this did not happen until they changed, this would not have happened. If they remained upright, upon respect of others, not having mockery, belittlement, abuse of others, the situation would not have changed upon them, but they changed. When you correct or refute a Sunni, do so with utmost adab, within the limits of the legislation. If they remained like this, the situation would not have changed upon them. But when they changed, the situation was made to change upon them. Do you want to experience the same thing as them? Preserve your time, wherever you may be in any markaz or any centre from the centres of the Sunnah. Show respect and manners.
