Mukhtasar Bukhari

Narrated from Sayyiduna Usama bin Zaid (may Allah be pleased with him) that Jibreel (peace be upon him) came to the Prophet Muhammad (peace and blessings be upon him) while Umm al-Mu'mineen Umm Salamah (may Allah be pleased with her) was present with him. He (Jibreel) began talking with the Prophet (peace and blessings be upon him), then got up (and left). The Prophet (peace and blessings be upon him) said to Umm Salamah (may Allah be pleased with her), "(Do you know) who that was?" (or asked a similar question). She replied, "That was Dihyah Kalbi" (who was a companion of the Prophet, peace and blessings be upon him). Umm Salamah (may Allah be pleased with her) said, "By Allah! I thought it was Dihyah until the Prophet (peace and blessings be upon him) addressed the people and referred to Jibreel (peace be upon him), and in the sermon he narrated those things which Jibreel (peace be upon him) had said to him."
