[Machine] Abdullah used to not consistently observe any act of worship except for performing the Witr prayer before the rak'ah.  

«كَانَ عَبْدُ اللهِ لَا يَقْنُتُ فِي شَيْءٍ مِنَ الصَّلَوَاتِ إِلَّا فِي الْوِتْرِ قَبْلَ الرَّكْعَةِ»  

[Machine] Abdullah used to not perform the morning prayer regularly, and when he did, he would perform the Witr prayer before the last unit.  

«كَانَ عَبْدُ اللهِ لَا يَقْنُتُ فِي صَلَاةِ الْغَدَاةِ وَإِذَا قَنَتَ فِي الْوِتْرِ قَنَتَ قَبْلَ الرَّكْعَةِ»  

[Machine] He used to offer voluntary prayers before the bowing (rak'ahs) in a prayer, but he did not offer voluntary prayers before the morning prayer.  

أَنَّهُ «كَانَ يَقْنُتُ فِي الْوِتْرِ قَبْلَ الرُّكُوعِ وَلَا يَقْنُتُ فِي صَلَاةِ الْفَجْرِ»
