Musannaf Ibn Abi Shaybah 1043 — A man on a journey with his wife

Sa'id bin Jubayr said: Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) was on a journey with a group of the Companions, and Sayyiduna Ammar bin Yasir (may Allah be pleased with him) was also with him. The people would put Sayyiduna Ibn Abbas (may Allah be pleased with them both) forward to lead the prayer because of his kinship with the Messenger of Allah (peace and blessings be upon him). One day Sayyiduna Ibn Abbas (may Allah be pleased with them both) led them in prayer, then turned towards them, smiled and said: "I had relations with a Roman slave-woman, then I led you in prayer in a state of major ritual impurity (janabah) after performing dry ablution (tayammum)."
