Through this chain of narration, from Muhammad ibn Ya’qub, from a group of our companions, from Sahl ibn Ziyad, from Ahmad ibn Muhammad ibn Abi Nasr, from Abdullah ibn Sinan, from Abu Abdullah عليه السلام, who said: Imam عليه السلام said: "The one who washes the deceased must perform ghusl. If someone kisses the deceased after their death while the body is still warm, there is no ghusl upon them. However, if they touch or kiss the deceased after the body has cooled, then they must perform ghusl. There is no issue in touching or kissing the deceased after having performed ghusl."
