Narrated Ibn Mas`ud:
حَدَّثَنِي سُلَيْمَانُ ، حَدَّثَنَا شُعْبَةُ ، عَنِ الْوَلِيدِ ،. وَحَدَّثَنِي عَبَّادُ بْنُ يَعْقُوبَ الأَسَدِيُّ ، أَخْبَرَنَا عَبَّادُ بْنُ الْعَوَّامِ ، عَنِ الشَّيْبَانِيِّ ، عَنِ الْوَلِيدِ بْنِ الْعَيْزَارِ ، عَنْ أَبِي عَمْرٍو الشَّيْبَانِيِّ ، عَنِ ابْنِ مَسْعُودٍ ـ رضى الله عنه ـ أَنَّ رَجُلاً، سَأَلَ النَّبِيَّ صلى الله عليه وسلم أَىُّ الأَعْمَالِ أَفْضَلُ قَالَ " الصَّلاَةُ لِوَقْتِهَا، وَبِرُّ الْوَالِدَيْنِ، ثُمَّ الْجِهَادُ فِي سَبِيلِ اللَّهِ " .
A man asked the Prophet (ﷺ) "What deeds are the best?" The Prophet (ﷺ) said: "(1) To perform the (daily compulsory) prayers at their (early) stated fixed times, (2) to be good and dutiful to one's own parents, (3) and to participate in Jihad in Allah's Cause."
