"We were with the Messenger of Allah on a campaign, and he said: 'Hasten to perform prayer on a cloudy day, for whoever misses the 'Asr prayer, all his good deeds will be in vain.'" (Using translation from Ibn Mājah 694)
كَانَ رَسُولُ اللهِ ﷺ فِي بَعْضِ غَزَوَاتِهِ فَقَالَ بَكِّرُوا بِالصَّلَاةِ فِي يَوْمِ الْغَيْمِ فَإِنَّهُ مَنْ تَرَكَ صَلَاةَ الْعَصْرِ حَبِطَ عَمَلُهُ
