Khallad b. as-Sa’ib on his father’s authority reported God’s messenger as saying, “Gabriel came to me and commanded me to order my companions to raise their voices in the talbiya.” (The tradition ends by saying they were to raise their voices bil-ihlal au at-talbiya. These are alternative words meaning the same thing, and therefore I have not given any alternative in the translation)
Malik, Tirmidhi, Abd Dawud, Nasa’i, Ibn Majah and Darimi transmitted it.
Sahl b. Sa‘d reported God’s messenger as saying, “No Muslim raises his voice in the talbiya without all on his right and left’, stones, or trees, or clods, doing the same till the earth is traversed on both sides,”
