The Imaam said, “My advice for every Muslim on the face of the earth, especially our brothers who share with us their affiliation to the blessed da’wah, that of the Book and the Sunnah on the methodology of the Pious Predecessors–I advise them and myself to fear Allaah, the Blessed and Most High, firstly, and then [advise them] to seek more beneficial knowledge as He the Most High said:
“And fear Allaah. And Allaah teaches you.” [Baqarah 2:282]
And [I advise them] to couple their meritorious knowledge which in our united opinion is that which does not digress from the Book, the Sunnah and the methodology of the Pious Predecessors, along with this knowledge of theirs and [along with] whatever increase in it they are able to seek–[I advise them] to couple that with action upon that knowledge, so that it will not be a proof against them but for them:
“The Day when there will not benefit [anyone] wealth or children. But only one who comes to Allaah with a sound heart.” [Shu’araa 26:88-89]
Thereafter I warn them from joining many of those who have left the path of the Salaf in many, numerous issues, something which can be termed as rebelling against the Muslims and their Jamaa’ahs [i.e., like the Khawaarij], rather we order them to be as the Prophet عليه الصلاة والسلام said in an authentic hadith, “And be servants of Allaah, brothers,” as Allaah the Blessed and Most High ordered you, and we should, as I said in a previous sitting and which I repeat again [here], and there is benefit in repeating [such points]–in our da’wah we should be gentle with those who oppose it and we should always and forever stand in line with His Saying, the Blessed and Most High:
“Invite to the way of your Lord with wisdom and good instruction, and argue with them in a way that is best,” [Nahl 16:125] and the ones who have the most right for us to use [such] wisdom with them are those who are the most severe in their conflict/disagreement with us in our doctrine and our aqidah so that we do not bring together [both] the weightiness of the true call [itself which] Allaah عز وجل favoured us with and the burden of ill manners in calling to Allaah عز وجل.
So I hope that all of our brothers in all Islamic countries imitate these Islamic manners and seek, by doing so, Allaah’s Face عز وجل [i.e., to do so sincerely] and not to want any reward or thanks [from the people].”
