Mishkat al-Masabih 4 Prayer كتاب الصلاة 497

وَعَن أم الدَّرْدَاء قَالَتْ: دَخَلَ عَلَيَّ أَبُو الدَّرْدَاءِ وَهُوَ مُغْضَبٌ فَقُلْتُ: مَا أَغْضَبَكَ؟ قَالَ: وَاللَّهِ مَا أَعْرِفُ مِنْ أَمْرِ أُمَّةِ مُحَمَّدٍ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ شَيْئًا إِلَّا أَنَّهُمْ يُصَلُّونَ جَمِيعًا. رَوَاهُ البُخَارِيّ

Umm ad-Darda’ said that on one occasion Abud Darda’ was angry when he came in, and on her asking what had made him angry, he replied, “I swear by God that the only good thing I know about Muhammad’s people is that they pray in congregation.”* * The suggestion is that they have become so corrupt that this is the only respect in which they obey the Prophet’s commands. Bukhari transmitted it.
