It is recommended to stop in Batha' of Dhul-Hulaifah and pray there when departing from Hajj and 'Umrah, or any time one passes through it

Abdullah b. 'Umar (Allah be pleased with them) reported that Allah's Messenger (ﷺ) made (his camel) kneel down (1: e. halt at the stony ground of Dhu'l-Hulaifa) and prayed there, and so did Abdullah b. Umar (Allah be pleased with them).

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أَنَاخَ بِالْبَطْحَاءِ الَّتِي بِذِي الْحُلَيْفَةِ فَصَلَّى بِهَا ‏.‏ وَكَانَ عَبْدُ اللَّهِ بْنُ عُمَرَ يَفْعَلُ ذَلِكَ ‏.‏

Nafi' reported that 'Abdullah b. Umar (Allah be pleased with them) used to halt his camel in the stony ground at Dhu'l-Hulaifa, where Allah's Messenger (ﷺ) used to make a halt (and pray).

وَحَدَّثَنِي مُحَمَّدُ بْنُ رُمْحِ بْنِ الْمُهَاجِرِ الْمِصْرِيُّ، أَخْبَرَنَا اللَّيْثُ، ح وَحَدَّثَنَا قُتَيْبَةُ، - وَاللَّفْظُ لَهُ - قَالَ حَدَّثَنَا لَيْثٌ، عَنْ نَافِعٍ، قَالَ كَانَ ابْنُ عُمَرَ يُنِيخُ بِالْبَطْحَاءِ الَّتِي بِذِي الْحُلَيْفَةِ الَّتِي كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُنِيخُ بِهَا وَيُصَلِّي بِهَا ‏.‏

Nafi' reported that when 'Abdullah b. 'Umar returned from Hajj or 'Umra he made his camel kneel down (i. e. halted) in the stony ground of Dhu'l-Hulaifa where Allah's Messenger (ﷺ) had made his camel halt.

وَحَدَّثَنَا مُحَمَّدُ بْنُ إِسْحَاقَ الْمُسَيَّبِيُّ، حَدَّثَنِي أَنَسٌ، - يَعْنِي أَبَا ضَمْرَةَ - عَنْ مُوسَى، بْنِ عُقْبَةَ عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ إِذَا صَدَرَ مِنَ الْحَجِّ أَوِ الْعُمْرَةِ أَنَاخَ بِالْبَطْحَاءِ الَّتِي بِذِي الْحُلَيْفَةِ الَّتِي كَانَ يُنِيخُ بِهَا رَسُولُ اللَّهِ صلى الله عليه وسلم ‏.‏

Salim (b. Abdullah b. 'Umar) reported on the authority of his father (Allah be pleased with them) that Allah's Messenger (ﷺ) was visited by (someone, i. e. an angel) during the fag end of the night at Dhu'l-Hulaifa, and it was said to him:

Verily it is a blessed stony-ground.

وَحَدَّثَنَا مُحَمَّدُ بْنُ عَبَّادٍ، حَدَّثَنَا حَاتِمٌ، - وَهُوَ ابْنُ إِسْمَاعِيلَ - عَنْ مُوسَى، - وَهُوَ ابْنُ عُقْبَةَ - عَنْ سَالِمٍ، عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أُتِيَ فِي مُعَرَّسِهِ بِذِي الْحُلَيْفَةِ فَقِيلَ لَهُ إِنَّكَ بِبَطْحَاءَ مُبَارَكَةٍ ‏.‏

Salim b. Abdullah b. Umar reported on the authority of his father (Allah be pleased with them) that Allah's Messenger (ﷺ) came to Dhu'l- Hulaifa in the heart of the valley at the fag end of the night, and it was said to him:

It is a blessed stony ground. Musa (one of the narrators) said: Salim made his came) halt at the mosque where 'Abdullah made his camel halt as seeking the place of stay of Allah's Messenger (ﷺ). It is, in fact, situated at a lower plain than the mosque, which stands in the heart of the valley, and it is between it (the mosque) (and Qibla) that that place (where Allah's Messenger (ﷺ) used to get down for rest and prayer) is situated.

وَحَدَّثَنَا مُحَمَّدُ بْنُ بَكَّارِ بْنِ الرَّيَّانِ، وَسُرَيْجُ بْنُ يُونُسَ، - وَاللَّفْظُ لِسُرَيْجٍ - قَالاَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ، أَخْبَرَنِي مُوسَى بْنُ عُقْبَةَ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ بْنِ عُمَرَ، عَنْ أَبِيهِ، أَنَّ النَّبِيَّ صلى الله عليه وسلم أُتِيَ وَهُوَ فِي مُعَرَّسِهِ مِنْ ذِي الْحُلَيْفَةِ فِي بَطْنِ الْوَادِي فَقِيلَ إِنَّكَ بِبَطْحَاءَ مُبَارَكَةٍ ‏.‏ قَالَ مُوسَى وَقَدْ أَنَاخَ بِنَا سَالِمٌ بِالْمُنَاخِ مِنَ الْمَسْجِدِ الَّذِي كَانَ عَبْدُ اللَّهِ يُنِيخُ بِهِ يَتَحَرَّى مُعَرَّسَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَهُوَ أَسْفَلُ مِنَ الْمَسْجِدِ الَّذِي بِبَطْنِ الْوَادِي بَيْنَهُ وَبَيْنَ الْقِبْلَةِ وَسَطًا مِنْ ذَلِكَ ‏.‏
