Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that when the Messenger of Allah (peace and blessings be upon him) was being lowered into the grave, Sayyiduna Abbas, Sayyiduna Ali, and Sayyiduna Fadl (may Allah be pleased with them) entered his blessed grave. The Ansari man who used to dig side graves (lahd) for the martyrs, he was the one who dug the side grave (lahd) for the Messenger of Allah (peace and blessings be upon him).
