Musannaf Ibn Abi Shaybah 12443 — Kissing the deceased after death

Abdullah al-Bahiyy said: Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) came after the death of the Prophet (peace and blessings be upon him), removed the cloth from his (peace and blessings be upon him) face, bent over him (peace and blessings be upon him) and kissed him, then said: "May my father and mother be sacrificed for you (peace and blessings be upon him)! How pure was your (peace and blessings be upon him) life, and how pure is your death!"
