Narrated Az-Zuhri that he visited Anas bin Malik at Damascus and found him weeping and asked him why he was weeping. He replied, "I do not know anything which I used to know during the life-time of Allah's Apostle except this prayer which is being lost (not offered as it should be)."
لاَ أَعْرِفُ شَيْئًا مِمَّا أَدْرَكْتُ إِلاَّ هَذِهِ الصَّلاَةَ وَهَذِهِ الصَّلاَةُ قَدْ ضُيِّعَتْ وَقَالَ بَكْرٌ حَدَّثَنَا مُحَمَّدُ بْنُ بَكْرٍ الْبُرْسَانِيُّ أَخْبَرَنَا عُثْمَانُ بْنُ أَبِي رَوَّادٍ نَحْوَهُ
