A narration with a similar meaning has already passed before this. It is narrated from Nafi' (may Allah have mercy on him) that Sayyiduna Ibn al-Zubayr (may Allah be pleased with them both) delayed the departure (from Muzdalifah towards Mina) until it had become well light, whereupon Sayyiduna Ibn Umar (may Allah be pleased with them both) said (by way of warning): "Is it the rising of the sun that is being waited for? Do these people still want to act according to the practice of the people of Jahiliyyah?" Then Sayyiduna Ibn Umar (may Allah be pleased with them both) departed from there and the people set off with him, after which Sayyiduna Ibn al-Zubayr (may Allah be pleased with them both) also set off.
This report (athar) is sahih (authentic) in its chain and mawquf (stopping at the Companion); however, since it contains an explanation of the procedure of the Prophetic Sunnah, it will be regarded as having the ruling of a marfu' hadith (one attributed to the Prophet).
