Abdullah ibn Zayd RA

Abdullah ibn Zayd RA was a Companion of the Ansar remembered above all for his dream of the adhan. After the Companions failed to agree on how to call people to prayer, he dreamed of a man teaching him its words, and the Prophet ﷺ declared it a true dream and had him teach them to Bilal RA, who had the louder voice; Umar RA then came saying he had dreamed the same. Beyond this little is recorded of him.
