Yahya related to me from Malik that Yahya ibn Said said that he heard Said ibn al-Musayyab say, "Shall I tell you what is better than much prayer and sadaqa?" They said, "Yes." He said, "Mending discord. And beware of hatred - it strips you (of your deen)."
يَقُولُ أَلاَ أُخْبِرُكُمْ بِخَيْرٍ مِنْ كَثِيرٍ مِنَ الصَّلاَةِ وَالصَّدَقَةِ قَالُوا بَلَى قَالَ إِصْلاَحُ ذَاتِ الْبَيْنِ وَإِيَّاكُمْ وَالْبِغْضَةَ فَإِنَّهَا هِيَ الْحَالِقَةُ
