Objection: How can their extinction be known and why is it not possible that in faraway lands, such as islands and corners of the earth, there may be nations believing in this creed, just as it is possible that there may be people believing in the word of Hasan that someone who commits a major sin is a hypocrite. Therefore, it cannot be claimed that the followers of this path no longer exist. It would have been possible if Muslims were few in the world with scant number of scholars, whereas Islam has spread and scholars are in abundance. So how can that be known? Reply: This assertion leads to the impossibility of discerning the consensus of the Ummah on any principle or idea, as it is always convenient to say that perchance there is someone in some remote periphery of the earth who disagrees with this. It follows that there might be someone in faraway parts of the earth, who says that eating hailstones does not violate a fast and that it is permissible for a fasting person to eat until sunrise; for the first was the view of Abu Talha Ansari and the second that of Huzaifah and Amash. Likewise, there are many other rulings of jurisprudence on which the companions and companions of companions (Tabiin) disagreed, and then later on disagreements disappeared and the Ummah united on a different view. Therefore, it is worthy to doubt that and mistrust any consensus on any question that has previously been a subject of disagreement.
