Sayyiduna Sa’ib bin Khallad (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said:“Jibreel (peace be upon him) came to me and said: Instruct your companions to recite the Talbiyah in a loud voice.”(Regarding one word here, the narrator is in doubt.) Sufyan says: Ibn Jurayj used to conceal a hadith from me. When Abdullah bin Abu Bakr came to us, I did not inform him about it. When he went to Madinah Munawwarah, I told him about it, so he said to me: O ‘Awf! Do you conceal ahadith from us? And when its people (i.e., its students) have departed, then you inform us about it. I will not narrate this narration from you; do you want me to narrate it from you? Then Abdullah bin Abu Bakr wrote to me in a letter. Then Abdullah bin Abu Bakr also wrote to Ibn Jurayj about this, so Ibn Jurayj narrated this narration in this way. Abdullah bin Abu Bakr had sent me this narration in a letter.
