In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Allaah [The Most High] guided mankind though Muhammad [sallal-laahu-alayhi-wasallam] and though what he brought of clear manifest evidences and guidance-a guidance that could not be described by those who were proficient in giving descriptions and surpassed the knowledge of those with great perception. So, though this guidance that was given to the Messenger of Allaah [sallal-laahu-alayhi- wasallam], Allaah [The Most High] opened the eyes of the blind ones, the ears of the deaf ones and the hearts of the heedless ones. Allaah [The Most High] united them upon one religion-[the religion of Islamic monotheism; Ibraaheem’s [alayhis-salaam] religion of pure monotheism]-after they had been in complete disunity, enmity towards one another, upon destructive and corrupt creeds. Allaah united their hearts and they became true brothers in Islaam by way of this great blessing. And thereafter everything that was worshiped besides Allaah-such as graves, trees, stones, graven images, idols etc- ceased to exist and all worship was carried out for Allaah (alone).
The people followed the true Religion of Islamic monotheism; they worshipped Allaah alone and established worship sincerely for Allaah, except those whom Allaah willed that they were to remain as people of polytheism, hypocrisy and followers of the altered and distorted previous scriptures. The darkness of shirk was dispelled and the banner of Tawheed was raised in the lands-amongst the Arabs and non-Arabs.
Allaah [The Most High] took away the soul of His Messenger [sallal-laahu-alayhi-wasallaam], whilst Islaam was established and in authority-superseding all other ways of life and creeds. Then the rightly guided khulafaa of the Messenger continued upon this path until the two powerful and great nations at the time-Rome and Persia-ended up in humiliation, degradation and in a state of fear after they had been in a state of security, and thus Caesar was restricted and besieged, and khosrau was subdued and destroyed.
So when the enemies of Islaam saw that they were unable to do away with this religion, they implanted their disbelieving agents within Islam, who pretended to be Muslims in order to foment confusion, trials and tribulations; and in order to spread shirk by exaggerating the status of the pious people and exalting their graves with [beliefs and practices] that were not ordained by Allaah.
So, this Ummah was put to trial through the plots of the [atheist, heretic and hypocrite] Abdullaah Bin Saba, who claimed Uloohiyyah [i.e. the right to be worship] for Ali Ibn Abee Taalib [radiyallaahu- anhu]. Abdullaah Bin As-Sabah’s followers were known as the Saaba-iyyah, and later on they were known as the rawaafid (shiites), the ismaaliyyah (shittes), the nusayriyah (shiites) and other than them amongst the Baatiniyyah. They used to worship the graves and the dead, and they used to build places of worship and domed [shaped] shrines upon these graves. So, by way of this they revived the practices of the Yahood, the Nasaaraa and the idol worshippers, and thus the practices of the worshippers of graves in this Muslim Ummah manifested itself in actions that were carried out by the rawaafid (shiites).
Secondly: The books of Greek philosophy that contained the ideas of grave and idol worship were translated into Arabic, so many of those who attributed themselves to Islam busied themselves with these books, such as the likes of Al- Faraabee (a) Ibn Sinaa Al-Hanafi (b) Naseer At- Toosee the advocator of disbelief and shirk (c) and other than them amongst those who played tricks with Islaam, just as Paul played tricks with Christianity.
They were influenced by the ideas of the Greek Philosophers, such as the creed of grave worship, so they became callers to grave worship through Greek Philosophy. The practices of these people was rife within the ranks of the people of rhetoric amongst the Hanafi Maatooreediyyah (d) and the Ash-ariyyah Kullaabiyyah due to busying themselves with the Books of the Philosophers; so they were influenced by the creed of grave worship. They became callers to grave worship and callers to the creed of the Jahmiyyah at the same time, such as the likes of Taftaazaanee Al-Hanafi [The Philosopher of the Maatooreediyyah and Grave worshipers] and Jurjaanee Al-Hanafi [a caller to superstition]
[a] Al-Faraabee: Al-Faraabee said that Philosophy is more perfect than Prophet hood. Shaikhul Islaam Ibn Taymiyyah (rahimahullaah) said about him: ‘’Misguided; a disbeliever’’ Ibn Sinaa adopted his books and ideas of disbelief. [For further details concerning Al- Faraabee, See Majmoo Al-Fataawaa 2/67—86] [Dar At-Ta’aarud 1/10] [Ighaathatul Luhfaan 2/372-373].
[a] Ibn Sinaa: Imaam Ibnu Salaah (rahimahullaah) said about him: ‘’He was a devil amongst the human devils.’’ [See Fataawaa Ibn Salaah 1/209] [Also see: ‘Ar-Radd Alal Mantaqiyyeen’ of Shaikhul Islaam Ibn Taymiyyah 278-279] [‘Ighaathatul Luhfaan’ of Imaam Ibnul Qayyim 2/373-380] [Bidaayah Wan-Nihaayah’ of Imaam Ibn Katheer 12/43]
[b] Naasir At-Toosee: He was a magician and a minister of the Tartars. He rejected the ‘resurrection’. For further details, see: As-Sawaa-iq Al-Mursalah of Imaam Ibnul Qayyim (rahimahullaah) 2/790; 3/1077-1078
[C]Followers of the Jahmi Abu Mansoor Al- Maatooreedi Al-Hanafi [For further details, see the Book of Shaikh Shamsud-deen al-Afghaanee titled: ‘Al-Maatooreediyyah’ 1/205—376] [d] Juhoodu Ulamaa Al-Hanafiyyah Fee Ibtaal Aqaa- id Al-Qubooriyyah Vol 1 pages 23-24
|Thirdly: A people appeared among the Muslims whilst manifesting asceticism. These people were more dangerous to the masses and more severe in misguidance. They were a people who appeared in the garb of the righteous people with tearful eyes smeared with kohl; long flowing beards; wearing elevated turbans, carrying large rosary beads and pretending to be calling to the Sunnah of the leader of the leaders of mankind [i.e. The Prophet (sallal-laahu-alayhi-wasallam)], whilst secretly practicing the disgraceful acts they inherited from the false and vanished religions. And among their plots was that they used to mix manifest lies with the authentic explanations of the Qur’aan and the authentic narrations in order to corrupt the clear evidences of the Qur’aan and the Sunnah. These deviant heretics are known as the [Hulooliyyah, Ittihaadiyyah Grave Worshippers (1)], such as the likes of Hallaaj (309AH), Ibnul Faarid (632AH) Ibn Arabi (638AH), Ibn Sab’een (669AH) etc
