Hazrat Khallad bin Sa’ib narrates from his esteemed father, Sayyiduna Sa’ib (may Allah be pleased with him), that the Noble Prophet (peace and blessings be upon him) said:“Jibreel (peace be upon him) came to me and said, ‘Command your companions to raise their voices while reciting the Talbiyah.’”In the narration of Ahmad, the words are“with Ihlaal and Talbiyah.”(Both mean to call out the Talbiyah.)
