Islamqa is not an authentic source for fatwas because the founder and author Muhammad Salih al-Munajid has been refuted by the scholars of the Sunnah.
“Shaikh Muqbil ibn Hadi al-Waad’iee rahimahullah during his treatment in the Kingdom was asked by one of the brothers who was in his sitting, ‘Were you present with al-Munajid?’ He said, ‘Yes’. He [then] said, ‘Do not be present with him for verily he is a suroori’.” End translation. [Taken from the Shaikh’s book Mahjooreen entry no. 152]
Shaikh Saleem al-Hilaali mentioned him from the people of bid’ah and hizbiyyah. [Taken from his book al-Jama’aat al-islaami pg. 118]
Shaikh Yahya ibn Ali al-Hajoori said, “Hizbi (ie. Muhammad al-Munajjid)” [taken from aloloom]
The Qutubiyyah are the followers of Sayyid Qutb, the deviant innovator, from the heads of ikhwan al-muslimeen (muslim brotherhood) and Khawaarij (the rebellious sect) in reality. Obviously this is a serious problem because Qutb called for the fighting of the Islamic government and claimed most of the Muslim world were in a state of Jahiliyyah (pre-islamic period) meaning they are not Muslims because they did not apply the rule of Allah. Also Qutb defamed Musa alayhi salam and denied the Mizan on the day of Judgement, etc.
Also Al-Munajid mentions Sayyid Qutb and Muhamamd Qutb among the books to read. And within his fataawa, he quotes Takfiri scholars like Sulaymaan al-‘Alwaan who is refuted and jailed. So we should beware of his site even though he quotes Shaikh Bin Baz and Shaykh Ibn uthaymeen, etc. Instead we should use the original sites of the scholars like alifta.com of the Permenant Commitee of Scholars of Saudi Arabia which was headed by Shaikh ibn Baz rahimahullah. It is in english and is very good.
