Attempting to unify the ranks with the groups and dealing with them

Question:
The questioner says: You know what is happening now in terms of disagreement among the groups existing among the people of the Sunnah. What is your opinion on attempting to unify the ranks with those groups, such as al-Tabligh and the Ikhwan, by conceding on some matters so that the ranks are unified? Also, what is the best way to deal with those groups? May Allah reward you with the best reward.

Answer:
The ranks cannot be unified, and we cannot gather except upon the Book of Allah and the Sunnah of His Messenger (peace and blessings be upon him) and what the Salaf of the Ummah were upon. So we say: Come to the Book of Allah, to the Sunnah of the Messenger of Allah (peace and blessings be upon him), and to what the Salaf of this Ummah were upon. Let us all proceed upon that, and let us reject the newly invented matters, religious innovations (bid'ah), superstitions, and the methodologies that so-and-so or so-and-so has invented. Let us reject these matters and make our methodology the Book of Allah, the Sunnah of His Messenger (peace and blessings be upon him), and what the Salaf of the Ummah were upon. Whoever accepts, praise be to Allah; and whoever does not accept, then his sin is upon himself. Yes.
