I was with Buraida on a cloudy day and he said, "Offer the ʿAsr prayer earlier as the Prophet ﷺ said, 'Whoever leaves the ʿAsr prayer will have all his (good) deeds annulled." (See Hadith No. 527 and 528)  

البخاري:٥٩٤حَدَّثَنَا مُعَاذُ بْنُ فَضَالَةَ قَالَ حَدَّثَنَا هِشَامٌ عَنْ يَحْيَى هُوَ ابْنُ أَبِي كَثِيرٍ عَنْ أَبِي قِلاَبَةَ أَنَّ أَبَا الْمَلِيحِ حَدَّثَهُ

قَالَ كُنَّا مَعَ بُرَيْدَةَ فِي يَوْمٍ ذِي غَيْمٍ فَقَالَ بَكِّرُوا بِالصَّلاَةِ فَإِنَّ النَّبِيَّ ﷺ قَالَ مَنْ تَرَكَ صَلاَةَ الْعَصْرِ حَبِطَ عَمَلُهُ
