أَخْبَرَنَا عَبْدَةُ بْنُ عَبْدِ اللَّهِ، عَنْ سُوَيْدٍ، عَنْ زُهَيْرٍ، عَنْ مُوسَى بْنِ عُقْبَةَ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّهُ وَهُوَ فِي الْمُعَرَّسِ بِذِي الْحُلَيْفَةِ أُتِيَ فَقِيلَ لَهُ إِنَّكَ بِبَطْحَاءَ مُبَارَكَةٍ .
It was narrated from 'Abdullah bin 'Umar that: when the Messenger of Allah was in Dhul-Hulaifah someone came to him and he was told: "You are in a blessed valley.''(sahih)
