Guidance for Salafi groups in the event of disagreement

Question:
Your Excellency the Shaykh, one of the brothers says: Your Excellency the Shaykh, may Allah reward you with good and benefit us with you and your knowledge. We inform you that there are Salafi groups in some African countries, but we have begun to see that some of them are starting to fragment, with each group believing it is on the correct methodology. Sometimes there is harshness and hostility between some of them. So what is your guidance for them? May Allah keep your words on the right path?

Answer:
Disagreement occurs, and praise be to Allah, disagreement occurs in understanding and in ijtihad (independent legal reasoning). However, this disagreement is resolved by returning to the Book of Allah the Exalted If you and I disagree, we do not remain in our disagreement, with each claiming to be on the truth and declaring the other misguided and erroneous. We do not return to the Book and the Sunnah to judge by the Qur'an and the Sunnah. Whoever the Qur'an and the Sunnah testify to as being correct, we follow, and we leave the one who contradicts him. This does not lead to hostility among Muslims. Disagreement does not lead to hostility except when accompanied by fanaticism. What causes hostility is fanaticism. But when there is a return to the Book of Allah and the Sunnah of His Messenger (peace and blessings be upon him), the disagreement is removed, by the permission of Allah.
