Sahih al-Bukhari 25:23
Narrated Musa bin `Uqba:
Salim bin `Abdullah's father said, "The Prophet (ﷺ) said that while resting in the bottom of the valley at Muarras in Dhul-Hulaifa, he had been addressed in a dream: 'You are verily in a blessed valley.' " Salim made us to dismount from our camels at the place where `Abdullah used to dismount, aiming at the place where Allah's Messenger (ﷺ) had rested and it was below the Mosque situated in the middle of the valley in between them (the residence) and the road.

حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي بَكْرٍ، حَدَّثَنَا فُضَيْلُ بْنُ سُلَيْمَانَ، حَدَّثَنَا مُوسَى بْنُ عُقْبَةَ، قَالَ حَدَّثَنِي سَالِمُ بْنُ عَبْدِ اللَّهِ، عَنْ أَبِيهِ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ رُئِيَ وَهُوَ فِي مُعَرَّسٍ بِذِي الْحُلَيْفَةِ بِبَطْنِ الْوَادِي قِيلَ لَهُ إِنَّكَ بِبَطْحَاءَ مُبَارَكَةٍ. وَقَدْ أَنَاخَ بِنَا سَالِمٌ، يَتَوَخَّى بِالْمُنَاخِ الَّذِي كَانَ عَبْدُ اللَّهِ يُنِيخُ، يَتَحَرَّى مُعَرَّسَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَهُوَ أَسْفَلُ مِنَ الْمَسْجِدِ الَّذِي بِبَطْنِ الْوَادِي، بَيْنَهُمْ وَبَيْنَ الطَّرِيقِ وَسَطٌ مِنْ ذَلِكَ.
