Oh noble Shaykh may Allah give you success. Is it correct what some people say, that criticizing the people of innovation such as the sufis and other than them is from the reasons that separates the people and divides the Muslim Ummah?
Yes! We want to separate from the innovator and the pagans and the grave worshippers. We do not want them to unite with us. No one will gather with us except for the people of Tawheed; this is what we want. This is the intentional division. Allah made a separation between the believers and the disbelievers.
أَفَمَنْ كَانَ مُؤْمِنًا كَمَنْ كَانَ فَاسِقًا لَا يَسْتَوُونَ
Is then he who believes like the one who is rebellious and wicked? Not equal are they. (As Sajdah 32:18)
أَمْ نَجْعَلُ الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ كَالْمُفْسِدِينَ فِي الْأَرْضِ أَمْ نَجْعَلُ الْمُتَّقِينَ كَالْفُجَّارِ
Shall We treat those who believe and work deeds of righteousness, the same as those who do mischief on earth? Shall We treat those who guard against evil, the same as the wicked? (Sad 38:28)
We intend this. We intended that those who do not accept the truth separate from us and we disassociate from them a clear disassociation.
