Some people from Najd came to the Messenger of Allah ﷺ while he was at Arafah and questioned him. He ordered an announcer to proclaim, "The Hajj is Arafah. Whoever arrives on the night of Jam before the break of dawn has caught the Hajj. The days of Mina are three. Whoever hurries to leave in two days has committed no sin, and whoever delays has committed no sin."Muhammad said that Yahya added, "He mounted a man behind him on his riding animal, and that man made the announcement."
حدثنا محمد بن بشار حدثنا يحيى بن سعيد وعبد الرحمن بن مهدي قالا حدثنا سفيان عن بكير بن عطاء
أن ناسا من أهل نجد أتوا رسول الله ﷺ وهو بعرفة فسألوه فأمر مناديا فنادى الحج عرفة من جاء ليلة جمع قبل طلوع الفجر فقد أدرك الحج أيام منى ثلاثة فمن تعجل في يومين فلا إثم عليه ومن تأخر فلا إثم عليه قال محمد وزاد يحيى وأردف رجلا فنادى
Its chain of transmission is sahih. Abu Dawud narrated it in the chapters on Hajj rites, in the chapter of one who does not reach Arafah, hadith no. 1949, as did Ibn Majah, hadith no. 3015, and Nasai, 5/256, hadith no. 3019, from the hadith of Sufyan Thawri, with the same wording, and he made clear that he heard it directly. Ibn Khuzayma graded it sahih, hadith no. 2822, as did Ibn Hibban (al-Ihsan), no. 3881, and Hakim, 1/278, 463, 464, and Dhahabi agreed with him.
