In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Shaikh Shamsuddeen Al-Afghaaniy [rahimahumallaah] said:
Allaah [The Most High] guided mankind through Muhammad [sallal-laahu-alayhi-wasallam] and the clear manifest evidences given to him [sallal-laahu-alayhi-wasallam] – a guidance that could not be described by those who were well versed in the art of descriptions and [a guidance] that surpassed the knowledge of those with great perception. And by way of this guidance, 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 on one religion-[the religion of Islamic monotheism] – and prior to that they were in complete disunity, enmity towards one another and followed corrupt creeds. Allaah united their hearts, and thus they became true brothers in Islaam by way of this great blessing. Thereafter, everything worshipped besides Allaah, such as graves, trees, stones and idols ceased to exist and all worship was established for Allaah alone. [Many] people followed the true Religion of Islamic monotheism and worshipped Allaah alone, 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 polytheism was dispelled and the banner of Tawheed was raised in the lands-amongst the Arabs and non-Arabs.
Allaah’s Messenger [sallal-laahu-alayhi-wasallaam] passed away, whilst Islaam was established and in authority-superseding all other ways of life and creeds. Then the rightly guided khulafaa of the Messenger [Abu Bakr, Umar, Uthmaan and Ali (radiyallaahu-anhum)] continued to adhere to the path of the Messenger [sallal-laahu-alayhi-wasallam] 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 [or Chosroes] was subdued and destroyed.
Beginning of the Plot against Islaam
When the enemies of Islaam saw that they were unable to do away with this religion, they implanted their disbelieving agents within it – those who pretended to be Muslims in order to kindle confusion, trials and tribulations, and spread polytheism by exaggerating the status of the pious people and exalting their graves through [beliefs and practices] that were not ordained by Allaah. So, the Ummah [Islamic Nation] was put to trial through the plots of the [atheist, heretic and hypocrite] Abdullaah Bin Saba, who claimed Uloohiyyah for Ali Ibn Abee Taalib [i.e. that Ali (the cousin of the Prophet) had the right to be worshipped besides Allaah]. Abdullaah Bin As- Sabah’s followers were known as the Saba’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 worshipped the graves and its inhabitants, and built places of worship and shrines upon those graves. So, through these practices, they revived the (corrupt ancient practices) of those Jews, Christians and the idol worshippers (who deviated from the straight path of the Prophets and Messengers of Allaah). This is how the practices of the worshippers of graves in this Muslim Nation manifested itself through the practices initiated by the rawaafid (shiites). [NB: The majority of the rawaafid Shiites presently live in Iran & Iraq, and their leader is Khumeini]
Secondly: The books of Greek philosophy that propagated 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 –an advocate of disbelief and polytheism (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, 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. 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]
[b] 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]
[c] 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
[d] 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]
Thirdly: A people who were more dangerous and misguided than the aforementioned groups emerged amongst the Muslims with a manifestation of asceticism. They appeared in the garb of righteousness – with tearful eyes, long flowing beards, elevated turbans, carrying large rosary beads and pretended to be calling to the Sunnah of the Prophet [sallal-laahu-alayhi-wasallam], whilst they secretly practised the disgraceful acts inherited from false religions. They attempted to mix blatant lies with the Qur’aan and the authentic narrations in order to corrupt the clear evidences found in the Qur’aan and the Sunnah. These deviant heretics are known as the Hulooliyyah, Ittihaadiyyah Grave Worshipers (1)], such as the likes of Hallaaj (309AH), Ibnul Faarid (632AH) Ibn Arabi (638AH), Ibn Sab’een (669AH) etc [Source: Juhoodu Ulamaa Al-Hanafiyyah Fee Ibtaal Aqaa-id Al-Qubooriyyeen’ of Shaikh Shamshud-deen As-Salafi Al-Afghaanee’ Vol 1 page 19-25]
Ibn Sinaa [The Heretic]
Question to Shaikh Saaleh Al-Fawzaan: What is your view regarding the one who praises Ibn Sinaa and places him within the ranks of the Muslim scholars?
Answer: Either this person is ignorant and is unaware of Ibn Sinaa’s state of affairs, therefore it is not appropriate that he should speak, rather it is obligated on him to keep quiet; or he is aware of Ibn Sinaa’s state of affairs and disbelief, so he affirms that for Ibn Sinaa and thus the ruling that applies to Ibn Sinaa is applicable to him, and Allaah’s refuge is sough; because he affirms Ibn Sinaa’s disbelief and praises him. This is very dangerous. [Ref 1] But some people praise Ibn Sinaa only due to the fact that he was a physician – praised due to a worldly science. And amongst the disbelievers, there are those who are more proficient than him in this field. But why do they mention Ibn Sinaa in particular? They say that because he attributes himself to Islaam and this is a credit to the Islaam. Therefore, we say: Islaam is free from Ibn Sinaa and not in need of him. He is not to be praised because he is a Baatini, a philosopher, Mulhid [Ref 2] [At-Taleeqaat Al-Mukhtasar Alaa Qaseedah An-Nooniyyah 3/1328]
