[Machine] From the Prophet ﷺ , that he said: "None of you should come to prayer while he is angry, and no one of you should exclude others from supplicating along with him. So whoever does that, he has betrayed them."  

أحمد:٢٢٢٤١حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ حَدَّثَنِي مُعَاوِيَةُ بْنُ صَالِحٍ حَدَّثَنِي السَّفْرُ بْنُ نُسَيْرٍ الْأَزْدِيُّ عَنْ يَزِيدَ بْنِ شُرَيْحٍ الْحَضْرَمِيِّ عَنْ أَبِي أُمَامَةَ

عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ لَا يَأْتِي أَحَدُكُمُ الصَّلَاةَ وَهُوَ حَاقِنٌ وَلَا يَؤُمَّنَّ أَحَدُكُمْ فَيَخُصَّ نَفْسَهُ بِالدُّعَاءِ دُونَهُمْ فَمَنْ فَعَلَ فَقَدْ خَانَهُمْ
