The Prophet ﷺ had a dream in the last portion of the night when he was sleeping at Dhul-Hulaifa. (I n the dream) it was said to him, "You are in a blessed Batha' (i.e., valley).  

عَنِ النَّبِيِّ ﷺ أَنَّهُ أُرِيَ وَهْوَ فِي مُعَرَّسِهِ بِذِي الْحُلَيْفَةِ فَقِيلَ لَهُ إِنَّكَ بِبَطْحَاءَ مُبَارَكَةٍ  

Verily it is a blessed stony-ground.  

أَنَّ رَسُولَ اللَّهِ ﷺ أُتِيَ فِي مُعَرَّسِهِ بِذِي الْحُلَيْفَةِ فَقِيلَ لَهُ إِنَّكَ بِبَطْحَاءَ مُبَارَكَةٍ  

when the Messenger of Allah was in Dhul-Hulaifah someone came to him and he was told: "You are in a blessed valley.''(sahih)  

عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ وَهُوَ فِي الْمُعَرَّسِ بِذِي الْحُلَيْفَةِ أُتِيَ فَقِيلَ لَهُ إِنَّكَ بِبَطْحَاءَ مُبَارَكَةٍ  

[Machine] He informed him that the Messenger of Allah ﷺ came to his wedding, and it was said to him, "Indeed you are in a blessed place."  

أَخْبَرَهُ أَنَّ رَسُولَ اللهِ ﷺ أَتَى فِي مُعَرَّسِهِ فَقِيلَ لَهُ إِنَّكَ فِي بَطْحَاءَ مُبَارَكَةٍ  

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 Messenger of Allah 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 Apostle used to get down for rest and prayer) is situated. (Using translation from Muslim 1346b)  

أَنَّ رَسُولَ اللهِ ﷺ أُتِيَ وَهُوَ فِي الْمُعَرَّسِ مِنْ ذِي الْحُلَيْفَةِ فِي بَطْنِ الْوَادِي فَقِيلَ إِنَّكَ فِي بَطْحَاءَ مُبَارَكَةٍ
