Ahmad ibn Muhammad ibn Isa narrated from his father from Abdillah ibn al-Mughira from Abdillah ibn Muskan from al-Halabi from Abu Abdillah عليه السلام, peace be upon him. Imam al-Sadiq عليه السلام said: “If a man catches one or two takbirs from the prayer over the deceased (Salat Al Mayyit), then let him make up what remains consecutively.”
