Shaykh Muhammad bin Haadee is amongst those whom the Hajaawirah Haddaadiyyah let loose their tongues when he spoke about Yahya al-Hajuri's revilements, and those of his poets and students, upon the people of knowledge. In responding to their activities, the Shaykh stated (this is recorded and well-spread and can be found here on Sahab.Net):
البَابُ الثَّانِي، فِيهِ مَـجْمُوعَةٌ في هَذَا الـمَوْقِع الذِي يُكْتَبُ فِيهِ بِاسْمِ دَارِ الحدِيثِ بِدَمَّاج، جَهَلَةٌ جَهْلاً مُرَكَّبًا، وَكَـذَّابِيـنَ، جَهَلَةٌ جَهْلاً مُرَكَّبًا، وَكَـذَّابِيـنَ، أَمَّا الـجَهْلُ الـمُرَكَّبُ، فَالـجَاهِلُ جَهْلاً مُرْكَّبًا فَهُوَ الذِي لاَ يَدْرِي، وَلاَ يَدْرِي أَنـَّـهُ لاَ يَدْرِي، جَاهِلٌ وَيَـجْهَلُ أَنـَّـهُ جَاهِلٌ، وَلِلأَسَفِ يَحي الحجُورِي يُؤَيِّدُهُمْ في كِتَابَاتِهِمْ
The second angle: There is a group on this website in which writings are made in the name of Dar al-Hadeeth in Dammaj, ignoramuses with compound ignorance, liars, ignoramuses with compound ignorance, liars. As for compound ignorance, then it is the ignoramus with compound ignorance, he is the one who does not know that he does not know, an ignoramus, ignorant that he is ignorant. And sadly, Yahya al-Hajuri supports them in their writings...
The website of al-Oloom has been the springboard for the Haddaadi manhaj and for activities arising from the ghuluww and hizbiyyah for Yahya al-Hajuri and his manhaj. Scathing attacks been launched from this website against the Major Scholars such as Shaykh Rabee bin Haadee. When al-Hajuri makes the likes of this speech about Shaykh Rabee' (see this article for evidence), "affaak (fabricator)", "kadhdhaab (liar)", "speaks out of following desires and shaytaan", "strives to set up a hizbee centre in Fayoosh", "person of destructive calamities", "calumniator", "the desires fester and flow in him", "may Allaah cut your tongue", "may Allaah fight you", "put my efforts and your efforts on the scale and we will see whose is more..." And that's just for Shaykh Rabee! What do you imagine for others? Al-Hajuri says "an old woman's fart" about one of the Shaykhs of Madinah, and "may you perish, just as the two hands of Abu Lahab perished and perish he!" to another of those Shaykhs. So when this is al-Hajuri, recorded with his own voice, then what do you expect from his students, poets and followers towards the Scholars of Ahl al-Sunnah, their students and followers. You would expect what has been coming from the al-Oloom website (Arabic and English) from certain factions amongst them, and which has been largely met with acceptance from the rest of them.
