I came to the Prophet ﷺ while he was at Arafah. A group of people from Najd came and appointed one of their men to call out, asking the Messenger of Allah ﷺ, "How is the Hajj performed?"The Messenger of Allah instructed a man to announce, "Hajj is the day of Arafah. Whoever arrives before the dawn prayer on the night of Jam has completed his Hajj. The days of Mina are three. 'Whoever hastens to leave in two days, there is no sin upon him, and whoever delays, there is no sin upon him' [Baqarah 2:203]."Then he mounted a man behind him, who began calling out this announcement.
أتيت النبي ﷺ وهو بعرفة فجاء ناس أو نفر من أهل نجد فأمروا رجلا، فنادى رسول الله ﷺ كيف الحج؟ فأمر رسول الله رجلا، فنادى: الحج يوم عرفة من جاء قبل صلاة الصبح من ليلة جمع فتم حجه أيام منى ثلاثة: {فمن تعجل في يومين فلا إثم عليه ومن تأخر فلا إثم عليه}. قال: ثم أردف رجلا خلفه فجعل ينادي بذلك.
Abu Dawud (1949), Tirmidhi (889), Nasai (210) (3047), and Ibn Majah (3015) all narrated it from the hadith of Sufyan Thawri, from Bukayr bin Ataa, from Abdul-Rahman bin Yamur Daili, and he mentioned it, the wording being that of Abu Dawud. Imam Ahmad narrated it (18774), and Ibn Khuzayma graded it sahih (2822), as did Ibn Hibban (3892) and Hakim (1/464), all through this route.Tirmidhi said, "This is the best hadith narrated by Sufyan Thawri." He also said, "Shubah narrated from Bukayr bin Ataa something similar to the hadith of Thawri. I heard Jarud say, I heard Wakee mention this hadith and say, this hadith is the mother of the rites of hajj."Hakim graded it sahih according to the criteria of the two sheikhs.
