The Companion trusted with the names of the hypocrites, and who urged one Quran for all.

The Prophet ﷺ told Hudhayfah the names of the hypocrites, and Umar would not pray over a man's funeral if Hudhayfah did not. On the freezing night of the Trench he crept into the enemy camp as a scout. Alarmed by quarrels over recitation in the army, he urged Uthman to unite the Muslims on one copy of the Quran.
