What is the ruling on the idea of patchwork in Islam, where one adopts the creed of the Salaf in matters of belief, but in da'wah says, "I will follow an Ikhwan or Tablighi approach, or something else"?

The questioner : What is the ruling on the idea of patchworking Islam? It means a person holds a Salafi creed because he studied and graduated from a Salafi methodology at a college of Da'wah, or a college of Shari'ah, or a college of Hadith, for example, because he studied a Salafi curriculum. But when it comes to da'wah, he says: "No, this methodology does not benefit us; rather, we will follow another approach, an Ikhwan or Tablighi one, or something else. It will not harm us because we are Salafi in creed, but as for methodology and da'wah, it is not suitable." Did the righteous Salaf distinguish between creed and the methodology of da'wah? May Allah reward you.

The Shaykh : The methodology, may Allah reward you, is built upon the creed. The methodology is built upon the creed. So whoever has a sound creed, his methodology will be sound without a doubt. This is because the Prophet (peace and blessings be upon him), when he mentioned that the Ummah would split into seventy-three sects, all in the Fire except one, his statement: means in creed, methodology, action, and everything. It is not possible for these to differ. For example, the Ikhwan, the Tablighi, the reformists, and others: if their methodology does not contradict the Shari'ah, there is no harm in it. But if it contradicts the Shari'ah, it must necessarily stem from a creed, because every action has an intention. If every action is with an intention, and a person adopts a methodology that contradicts the methodology of the Messenger of Allah (peace and blessings be upon him) and his Rightly Guided Successors, it means his creed is not sound. Otherwise, when the creed is sound, the methodology is sound.
Then, on this occasion, I would like to say: One of the trials that have befallen the Ummah, especially in the present time, is division and fragmentation. This person follows the methodology of so-and-so, and that person follows the methodology of so-and-so. If only they would leave one another alone! You do not find that everyone is not declaring the other misguided, and perhaps even declaring him a disbeliever, in matters that are not misguidance and not disbelief. This is a calamity that has struck the Islamic awakening, which we had hoped for good from a few years ago. Now, many of the youth are fragmented. I mean, perhaps this young brother who seeks the truth as he wants it is hated more than a person who is an open sinner. We ask Allah for safety. All of this is undoubtedly from the inspiration of Satan and the commands of Satan. It is obligatory upon us to unite with one another, to sit and investigate who is on the truth, and we support him, and who is on falsehood, and we clarify it to him. But if he says: "I do not know anything but this, and this is my ijtihad, and it has a basis in the Arabic language and in the Shari'ah," then we do not declare him misguided. Praise be to Allah, the matter is broad.
