وَعَنِ ابْنِ عَبَّاسٍ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «ثَلَاثَةٌ لَا تُرْفَعُ لَهُم صلَاتهم فَوق رؤوسهم شِبْرًا: رَجُلٌ أَمَّ قَوْمًا وَهُمْ لَهُ كَارِهُونَ وَامْرَأَةٌ بَاتَتْ وَزَوْجُهَا عَلَيْهَا سَاخِطٌ وَأَخَوَانِ مُتَصَارِمَانِ»
a man who acts as imam for people when they do not like him, a woman with whom her husband is displeased throughout the night, and two brothers* who are disunited. * The word here is most probably used in the widest sense, meaning two Muslims.
