حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، عَنْ عَلِيِّ بْنِ الْمُبَارَكِ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ أَبِي سَلَمَةَ، عَنْ عُبَادَةَ بْنِ الصَّامِتِ، قَالَ سَأَلْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ عَنْ قَوْلِ اللَّهِ سُبْحَانَهُ ‏{لَهُمُ الْبُشْرَى فِي الْحَيَاةِ الدُّنْيَا وَفِي الآخِرَةِ}‏ ‏.‏ قَالَ ‏"‏ هِيَ الرُّؤْيَا الصَّالِحَةُ يَرَاهَا الْمُسْلِمُ أَوْ تُرَى لَهُ ‏"‏ ‏.‏
