Ibn 'Umar (Allah be pleased with him) reported that Messenger of Allah ﷺ and Abu Bakr and 'Umar observed halt at al-Abtah.  

أَنَّ النَّبِيَّ ﷺ وَأَبَا بَكْرٍ وَعُمَرَ كَانُوا يَنْزِلُونَ الأَبْطَحَ  

Messenger of Allah ﷺ halted at Muhassab and the Caliphs did the same after him.  

نَافِعٌ قَدْ حَصَّبَ رَسُولُ اللَّهِ ﷺ وَالْخُلَفَاءُ بَعْدَهُ  

Halt at al-Abtah is not the Sunnah. Messenger of Allah ﷺ halted there simply because it was easier for him to depart from there, when he left.  

نُزُولُ الأَبْطَحِ لَيْسَ بِسُنَّةٍ إِنَّمَا نَزَلَهُ رَسُولُ اللَّهِ ﷺ لأَنَّهُ كَانَ أَسْمَحَ لِخُرُوجِهِ إِذَا خَرَجَ  

This hadith is narrated on the authority of Hisham with the same chain of transmitters.  

عَنْ هِشَامٍ بِهَذَا الإِسْنَادِ مِثْلَهُ  

Messenger of Allah ﷺ halted there, for it is a place from where it was easy to depart.  

أَنَّ أَبَا بَكْرٍ وَعُمَرَ وَابْنَ عُمَرَ كَانُوا يَنْزِلُونَ الأَبْطَحَ قَالَ الزُّهْرِيُّ وَأَخْبَرَنِي عُرْوَةُ عَنْ عَائِشَةَ أَنَّهَا لَمْ تَكُنْ تَفْعَلُ ذَلِكَ وَقَالَتْ إِنَّمَا نَزَلَهُ رَسُولُ اللَّهِ ﷺ لأَنَّهُ كَانَ مَنْزِلاً أَسْمَحَ لِخُرُوجِهِ  

Halt at Muhassab is not something (significant from the point of view of the Shari'ah). It is a place of halt where Messenger of Allah (way peace be upon him) halted.  

لَيْسَ التَّحْصِيبُ بِشَىْءٍ إِنَّمَا هُوَ مَنْزِلٌ نَزَلَهُ رَسُولُ اللَّهِ ﷺ  

Messenger of Allah ﷺ did not command me to observe halt at al-Abtah when be departed from Mina, but I came and set up his (the Holy Prcphet's) tent (of my own accord) ; and he (Allah's Apostle) came and observed halt. This hadith is narrated through another chain of transmitters from Abu Rafi' who was (in charge) of the luggage of Allah's Apostle ﷺ.  

أَبُو رَافِعٍ لَمْ يَأْمُرْنِي رَسُولُ اللَّهِ ﷺ أَنْ أَنْزِلَ الأَبْطَحَ حِينَ خَرَجَ مِنْ مِنًى وَلَكِنِّي جِئْتُ فَضَرَبْتُ فِيهِ قُبَّتَهُ فَجَاءَ فَنَزَلَ قَالَ أَبُو بَكْرٍ فِي رِوَايَةِ صَالِحٍ قَالَ سَمِعْتُ سُلَيْمَانَ بْنَ يَسَارٍ وَفِي رِوَايَةِ قُتَيْبَةَ قَالَ عَنْ أَبِي رَافِعٍ وَكَانَ عَلَى ثَقَلِ النَّبِيِّ ﷺ  

God willing, we will get down tomorrow, at Khaif of Banu Kinanah, the place where they had taken an oath on unbelief.  

عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ نَنْزِلُ غَدًا إِنْ شَاءَ اللَّهُ بِخَيْفِ بَنِي كِنَانَةَ حَيْثُ تَقَاسَمُوا عَلَى الْكُفْرِ  

Messenger of Allah ﷺ said to us as we were at Mina: We would observe halt tomorrow at-Khaif of Banu Kinanah, where (the polytheists) had taken an oath on unbelief, and that was that the Quraish and Banu Kinanah had, pledged against Banu Hashim and Banu Muttalib that they would neither marry nor do any transaction with them unless they deliver Messenger of Allah (way peace be upon him) to them. And (this pledge was) taken at this (place) Muhassab.  

لَنَا رَسُولُ اللَّهِ ﷺ وَنَحْنُ بِمِنًى نَحْنُ نَازِلُونَ غَدًا بِخَيْفِ بَنِي كِنَانَةَ حَيْثُ تَقَاسَمُوا عَلَى الْكُفْرِ وَذَلِكَ إِنَّ قُرَيْشًا وَبَنِي كِنَانَةَ تَحَالَفَتْ عَلَى بَنِي هَاشِمٍ وَبَنِي الْمُطَّلِبِ أَنْ لاَ يُنَاكِحُوهُمْ وَلاَ يُبَايِعُوهُمْ حَتَّى يُسْلِمُوا إِلَيْهِمْ رَسُولَ اللَّهِ ﷺ يَعْنِي بِذَلِكَ الْمُحَصَّبَ  

God willing, when Allah has granted us victory, our halt tomorrow will be at Khaif, where they (the unbelievers of Mecca) had taken an oath on unbelief.  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْزِلُنَا إِنْ شَاءَ اللَّهُ إِذَا فَتَحَ اللَّهُ الْخَيْفُ حَيْثُ تَقَاسَمُوا عَلَى الْكُفْرِ
