Nafi' said: When Ibn Umar (may Allah be pleased with them both) intended to set out for Makkah, he would apply an oil that had no fragrance, then he would come to the mosque of Dhu al-Hulayfah, pray two rak'ahs and mount; and when his mount stood up with him, he would say the talbiyah and say: "The Messenger of Allah (peace and blessings be upon him) did exactly this."
