Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: the Messenger of Allah (peace and blessings be upon him) set out from Madinah after combing his hair, applying oil, and putting on his lower garment (izar) and upper sheet, and his Companions did the same. He did not forbid any kind of lower garment, nor did he forbid wearing sheets, except saffron-dyed sheets. When he reached Dhu al-Hulayfah, he mounted his mount, and when it reached al-Bayda', he and his Companions said the talbiyah, and he garlanded his sacrificial animal. This was when five days of Dhu al-Qa'dah still remained. He reached Makkah on the 4th of Dhu al-Hijjah, performed tawaf of the House and of al-Safa and al-Marwah, and, since he had brought his sacrificial animals and garlanded them, he did not leave ihram. He stayed at al-Hajun in the upper part of Makkah, and he (peace and blessings be upon him) was in ihram for Hajj, and after performing tawaf of the Ka'bah he did not go near it until he returned from Arafah. He (peace and blessings be upon him) commanded his Companions "to perform tawaf of the House and of al-Safa and al-Marwah, then to cut the hair of their heads and leave ihram." This was for those who had not brought garlanded sacrificial animals; and whoever had his wife with him, she was lawful for him, and they also wore perfume and (ordinary) clothes.
