Overall meaning:
Usāmah ibn Zayd (may Allah be pleased with them both) rode behind the Prophet ﷺ on the journey from ʿArafah to Muzdalifah. He therefore knew better than anyone how the Prophet travelled on that stretch. When asked to describe it he replied: The Prophet would ride at an ʿanq—a calm, even pace—so as not to jostle the densely packed pilgrims and so that, after departing from that momentous station and moving toward al-Mashʿar al-Ḥarām (the Sacred Monument), he remained humble and submissive, clothed in tranquillity and dignity, hoping that his deeds would be accepted and thanking his Lord for the blessings by which Islam was strengthened and idolatry abased. Whenever he came upon an open space with no one in the way, he would urge his mount forward and quicken the pace a little, yet his reverence and humility never left him in any motion or stillness.

Points derived from the ḥadīth:

1. Usāmah ibn Zayd rode pillion behind the Prophet ﷺ from the time he left ʿArafah until he reached Muzdalifah, making him the person most familiar with the Prophet’s riding pace.
2. The Prophet ﷺ travelled at a measured pace—neither so slow as to impede progress nor so fast as to harm others—thus preserving both his own reverence and the safety of the pilgrims around him.
3. When he found an open stretch with no one present, he would make his mount move a little faster while remaining in full humility before Allah, mindful of Him and magnifying His rites and sacred sites.
4. The frivolity, haste, speed, and automobile racing seen among many pilgrims today run contrary to the sunnah and to the majesty, serenity, and dignity of Hajj.

This excessive haste brings about several violations: leaving the boundaries of ʿArafah before sunset, thereby imitating the polytheists; harm that befalls riders and their vehicles; quarrels and disputes that undermine the etiquette of Hajj; and many other evils that arise from rushing where haste has no place.
