صَحِيحُ الْبُخَارِيِّ
Sahih al-Bukhari 594
Times of the Prayers
To offer (the 'Asr prayers) earlier on a cloudy day
حَدَّثَنَا مُعَاذُ بْنُ فَضَالَةَ، قَالَ حَدَّثَنَا هِشَامٌ، عَنْ يَحْيَى ـ هُوَ ابْنُ أَبِي كَثِيرٍ ـ عَنْ أَبِي قِلاَبَةَ، أَنَّ أَبَا الْمَلِيحِ، حَدَّثَهُ قَالَ كُنَّا مَعَ بُرَيْدَةَ فِي يَوْمٍ ذِي غَيْمٍ فَقَالَ بَكِّرُوا بِالصَّلاَةِ فَإِنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ مَنْ تَرَكَ صَلاَةَ 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 (ﷺ) said, 'Whoever leaves the `Asr prayer will have all his (good) deeds annulled." (See Hadith No. 527 and 528)
