Striving to unite the Muslims on the saved sect to the best of one's ability

Question : May Allah bless you. If it is said to the one who tries to gather the scattered Muslims and free them to the word of truth, "You are merely weeping over pomegranates," how is that, when the truthful, veracious Messenger (peace and blessings be upon him) informed us that the Ummah will split? So try to know the truth and stick to the sect that is upon the truth. As for trying to gather them, even upon the word of truth, this attempt is one that he should support in the months. Because we are present in a section of reality; how is the answer to it?

Answer : The answer is as the Shaykh (may Allah have mercy on him) mentioned: the Messenger mentioned this as a warning. Therefore, he said, "They are all in the Fire except one; they are all in the Fire except one." So we gather what we can. But if we gather, can we gather the entire Ummah? That is not possible. But we gather what we can upon the saved sect.
