Silsilah as-Sahihah 995 — Saying Talbiyah aloud

It is narrated from Sayyiduna Zayd bin Khalid al-Juhani (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Jibril (peace be upon him) came to me and said: O Muhammad! Command your companions to recite the Talbiyah aloud, for it is one of the rites of Hajj."
