Chapter on the Prayer over the Dead

From him, from Muhammad ibn Sinan, from Talhah ibn Zayd, from Abu Abdillah عليه السلام, peace be upon him, who said: When Imam عليه السلام performed the funeral prayer over a woman and a man (together), He عليه السلام would place the woman in front (of the man) and the man behind (meaning closest to the imam of prayer). And when Imam عليه السلام performed the funeral prayer over a slave and a free man (together), he would place the slave in front (of the free man) and the free man behind (meaning closest to the imam of prayer). And when Imam عليه السلام performed the funeral prayer over a child and an elder (together), He عليه السلام would place the child in front (of the elder) and the elder behind (meaning closest to the imam of prayer).”
