Narrated 'Ata bin Yasar:
from a man among the people of Egypt who said: "I asked Abu Ad-Darda about this Ayah: For them is good news in the life of the present world (10:64). He said: 'No one asked me about since I asked the Messenger of Allah (ﷺ) about it, and he (ﷺ) said: "No one asked me about it other than you, since it was revealed. It is the righteous dream that the Muslims sees, or that it seen about him."
حَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، عَنِ ابْنِ الْمُنْكَدِرِ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ رَجُلٍ، مِنْ أَهْلِ مِصْرَ قَالَ سَأَلْتُ أَبَا الدَّرْدَاءِ عَنْ هَذِهِ الآيَةِ ‏:‏ ‏(‏ لَهُمُ الْبُشْرَى، فِي الْحَيَاةِ الدُّنْيَا ‏)‏ قَالَ مَا سَأَلَنِي عَنْهَا أَحَدٌ مُنْذُ سَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَنْهَا فَقَالَ ‏ "‏ مَا سَأَلَنِي عَنْهَا أَحَدٌ غَيْرُكَ مُنْذُ أُنْزِلَتْ فَهِيَ الرُّؤْيَا الصَّالِحَةُ يَرَاهَا الْمُسْلِمُ أَوْ تُرَى لَهُ ‏"‏ ‏.‏
