Some people among the residents of Najd came to the Messenger of Allah while he was at Arafat. They were questioning him, so he ordered a caller to proclaim: "The Hajj is Arafah. Whoever came to Jam during the night, before the time of Fajr, then he has attended the Hajj. The days of Mina are three, so whoever hastens (leaving after) two days, then there is no sin upon him, and whoever delays, then there is no sin upon him." Muhammad said: "Yahya added: 'And he took a companion rider to proclaim it.'"  

أَنَّ نَاسًا مِنْ أَهْلِ نَجْدٍ أَتَوْا رَسُولَ اللَّهِ ﷺ وَهُوَ بِعَرَفَةَ فَسَأَلُوهُ فَأَمَرَ مُنَادِيًا فَنَادَى الْحَجُّ عَرَفَةُ مَنْ جَاءَ لَيْلَةَ جَمْعٍ قَبْلَ طُلُوعِ الْفَجْرِ فَقَدْ أَدْرَكَ الْحَجَّ أَيَّامُ مِنًى ثَلاَثَةٌ فَمَنْ تَعَجَّلَ فِي يَوْمَيْنِ فَلاَ إِثْمَ عَلَيْهِ وَمَنْ تَأَخَّرَ فَلاَ إِثْمَ عَلَيْهِ قَالَ مُحَمَّدٌ وَزَادَ يَحْيَى وَأَرْدَفَ رَجُلاً فَنَادَى  

(Another chain) with a similar narration (as no. 889).  

عَنِ النَّبِيِّ ﷺ نَحْوَهُ بِمَعْنَاهُ وَقَالَ ابْنُ أَبِي عُمَرَ قَالَ سُفْيَانُ بْنُ عُيَيْنَةَ وَهَذَا أَجْوَدُ حَدِيثٍ رَوَاهُ سُفْيَانُ الثَّوْرِيُّ  

"I came to the Messenger of Allah at Al-Muzdalifah when he left for the Salat. I said: 'O Messenger of Allah! I came from the two mountains of (the tribe of) Tai, wearing out my mount and exhausting myself. By Allah! I did not leave a Habl (sand dune) without stopping on it. So is there Hajj for me?' The Messenger of Allah said: 'Whoever attends this Salat of ours, and stays here with us until departing, while he has stood during the night or the day before that at Arafat, then he has completed his Hajj and fulfilled his Tafath.'"  

أَتَيْتُ رَسُولَ اللَّهِ ﷺ بِالْمُزْدَلِفَةِ حِينَ خَرَجَ إِلَى الصَّلاَةِ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنِّي جِئْتُ مِنْ جَبَلَىْ طَيِّئٍ أَكْلَلْتُ رَاحِلَتِي وَأَتْعَبْتُ نَفْسِي وَاللَّهِ مَا تَرَكْتُ مِنْ حَبْلٍ إِلاَّ وَقَفْتُ عَلَيْهِ فَهَلْ لِي مِنْ حَجٍّ فَقَالَ رَسُولُ اللَّهِ ﷺ مَنْ شَهِدَ صَلاَتَنَا هَذِهِ وَوَقَفَ مَعَنَا حَتَّى نَدْفَعَ وَقَدْ وَقَفَ بِعَرَفَةَ قَبْلَ ذَلِكَ لَيْلاً أَوْ نَهَارًا فَقَدْ أَتَمَّ حَجَّهُ وَقَضَى تَفَثَهُ
