Is the hadith about the Ummah splitting into seventy-three sects authentic?

Question:
May Allah reward you, Your Eminence, father. The questioner says: These days, the hadith of the Prophet (peace and blessings be upon him) is being circulated, which in its meaning states that the splitting , is this hadith authentic or weak?

Answer:
Yes, in the aggregate of its chains, it is authentic. The scholars have written on collecting its chains, and it has become clear that it is an authentic hadith in the aggregate of its chains. But these people want the Ummah to be uniform, that no one has misguidance and no one has deviation, and that all people are the same. That is what they want.
They say there is no distinction between people; all people are human, all are the sons of Adam. That is what they want. They want to blur the religion, and they want to blur loyalty and disavowal, and they want to blur the classification of people as Allah classified them into a believer, a disbeliever, an open sinner, and a hypocrite. They want this. They want to make people one thing.
Yes, and this will never happen. People will not be one thing. People are diverse. Yes.
