What is the ruling for the one who makes mockery of the students of knowledge and the Ulamaa, describing them with harshness, sternness and that they do not understand the modern day affairs?
All praise is due to Allah, may the Salaah of Allah be upon our Prophet Muhammad, his family, companions and those who align themselves with him. I bear witness that none has the right to be worshipped except Allah alone, without any partners. And I bear witness that Muhammad is the servant of Allah and His Messenger.
As to what follows:
When the person belittles the people of knowledge for their personal selves, this is considered a clear sin. However, if the person belittles them and he intends by this belittlement, belittling the Book and the Sunnah, this is considered disbelief.
However, that which we advise our brothers with is to be patient, they should be deliberate in the affairs and they should learn. For indeed these individuals who make mockery, the ending affair of their mockery will come upon them, In shaa Allah. Allah says:
Oh you who believe, be patient, forbearing, remain firm and fear Allah in order that you may be successful.[Aali 'Imraan:200]
This is what Nooh (alayhis salaam) said when his people passed by him making mockery of him while he was making the ark:
If you make mockery of us (now) we will (one day) make mockery of you just as you made mockery of us.[Hud:38]
Therefore, I advise you to be patient and know that:
The good and evil are not the same. Repel with that which is better, if there is between you and him enmity, he will become as if he is a close friend.[Fussilaat:34]
Therefore be patient, may Allah bless you. Allah says:
And we have made from them leaders guiding by our command when they were patent and they had certainty regarding our verses/signs.[Ash-Sajdah:32]
I advise you to let this mockery be a means of motivation for you to hold on to the Sunnah. Let it be a means for you to strive hard in seeking the beneficial knowledge. If we were to obey those individuals who make mockery of us, we would leave off (seeking) the knowledge. We would leave off calling to Allah. Those who are better than us have been mocked. The Prophet ﷺ was mocked of as well as the Prophets before him. Therefore, it is upon us to be patient.
From the blessing of Allah upon you, if mockery is being made of you due to the Da'wah, then you are on a magnificent level. Indeed, it was said to the Prophet ﷺ that he was insane and that he was a sorcerer. Don't pay no mind (to the mockery) may Allah perserve you. Allah said:
Tomorrow they will come to know, who is the liar, the insolent one![Qamar:26]
And those who do wrong will come to know by what overturning they will be overturned.[Ash-Shuara'a:227]
And with the praise being for Allah the people are increased in hatred when they see them making mockery of Ahlus Sunnah and Allah is the one who the help is sought from.
