حَدَّثَنَا مُعَاذُ بْنُ فَضَالَةَ ، قَالَ : حَدَّثَنَا هِشَامٌ ، عَنْ يَحْيَى هُوَ ابْنُ أَبِي كَثِيرٍ ، عَنْ أَبِي قِلَابَةَ ، أَنَّ أَبَا الْمَلِيحِ حَدَّثَهُ ، قَالَ : كُنَّا مَعَ بُرَيْدَةَ فِي يَوْمٍ ذِي غَيْمٍ ، فَقَالَ : بَكِّرُوا بِالصَّلَاةِ فَإِنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، قَالَ : " مَنْ تَرَكَ صَلَاةَ الْعَصْرِ حَبِطَ عَمَلُهُ " .
Narrated Ibn Abu Malih [??]: I was with Buraida on a cloudy day and he said, "Offer the `Asr prayer earlier as the Prophet said, 'Whoever leaves the `Asr prayer will have all his (good) deeds annulled." (See Hadith No. 527 and 528)
