Qasim bin Abd al-Rahman bin Abdullah bin Mas'ud (may Allah be pleased with him) said: The first person to learn the Qur'an from the mouth of the Messenger of Allah was Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him); the first person to build a mosque in which prayer is offered was Sayyiduna Ammar bin Yasir (may Allah be pleased with him); and the first person to give the call to prayer (adhan) was Sayyiduna Bilal (may Allah be pleased with him).
(Allamah al-Haythami says:) I say: This hadith will come in full in the chapter on Jihad, in the section on archery, if Allah wills, and its chain is munqati' (broken).
