It is narrated from Sayyiduna Zayd bin Arqam (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "What an excellent man Bilal is! He is the master of the mu'adhdhins (callers to prayer), and none but a mu'adhdhin will follow him; and on the Day of Resurrection the mu'adhdhins will have the longest (most prominent) necks of all people." Husam is alone in narrating this hadith.

It is narrated from Sayyiduna Buraydah (may Allah be pleased with him) that one day in the morning the Messenger of Allah (peace and blessings be upon him) called Bilal (may Allah be pleased with him) and said: "O Bilal! By what deed did you precede me into Paradise? Last night I entered Paradise and heard the sound of your footsteps ahead of me. Then I came to a square, lofty palace of gold, and I asked: 'Whose palace is this?' They said: 'A man from the Ummah of Muhammad.' I said: 'I am Muhammad; whose palace is this?' They said: 'An Arab's.' I said: 'I am an Arab; whose is it?' They said: 'A man of Quraysh.' I said: 'I am of Quraysh; whose is it?' They said: 'Umar bin al-Khattab's.'" At this Bilal (may Allah be pleased with him) said: O Messenger of Allah! Whenever I have given the adhan, I have always prayed two rak'ahs (voluntary prayer) after it, and whenever I have happened to lose my ablution, I have performed ablution right then. The Messenger of Allah (peace and blessings be upon him) said: "It is because of this." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

Sayyiduna Amr bin Abasah (may Allah be pleased with him) narrates: I saw the Prophet (peace and blessings be upon him) while he was staying at Ukaz, and I asked: Who is with you in this matter (the religion)? He (peace and blessings be upon him) said: "Two men: Abu Bakr and Bilal." So I accepted Islam, and I found myself the fourth person to have accepted Islam. This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
