Not offering As-Salat (the prayers) at its stated fixed time

Narrated Ghailan:

Anas said, "I do not find (now-a-days) things as they were (practiced) at the time of the Prophet." Somebody said "The prayer (is as it was.)" Anas said, "Have you not done in the prayer what you have done?

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، قَالَ حَدَّثَنَا مَهْدِيٌّ، عَنْ غَيْلاَنَ، عَنْ أَنَسٍ، قَالَ مَا أَعْرِفُ شَيْئًا مِمَّا كَانَ عَلَى عَهْدِ النَّبِيِّ صلى الله عليه وسلم‏.‏ قِيلَ الصَّلاَةُ‏.‏ قَالَ أَلَيْسَ ضَيَّعْتُمْ مَا ضَيَّعْتُمْ فِيهَا‏.‏

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 Messenger (ﷺ) except this prayer which is being lost (not offered as it should be)."

حَدَّثَنَا عَمْرُو بْنُ زُرَارَةَ، قَالَ أَخْبَرَنَا عَبْدُ الْوَاحِدِ بْنُ وَاصِلٍ أَبُو عُبَيْدَةَ الْحَدَّادُ، عَنْ عُثْمَانَ بْنِ أَبِي رَوَّادٍ، أَخِي عَبْدِ الْعَزِيزِ قَالَ سَمِعْتُ الزُّهْرِيَّ، يَقُولُ دَخَلْتُ عَلَى أَنَسِ بْنِ مَالِكٍ بِدِمَشْقَ وَهُوَ يَبْكِي فَقُلْتُ مَا يُبْكِيكَ فَقَالَ 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.‏
