Sunan an-Nasai
أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ، قَالَ حَدَّثَنَا سُفْيَانُ، قَالَ حَدَّثَنَا أَبُو مُعَاوِيَةَ النَّخَعِيُّ، سَمِعَهُ مِنْ أَبِي عَمْرٍو، عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ، قَالَ سَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم أَىُّ الْعَمَلِ أَحَبُّ إِلَى اللَّهِ عَزَّ وَجَلَّ قَالَ " إِقَامُ الصَّلاَةِ لِوَقْتِهَا وَبِرُّ الْوَالِدَيْنِ وَالْجِهَادُ فِي سَبِيلِ اللَّهِ عَزَّ وَجَلَّ " .
It was narrated that 'Abdullah bin Mas'ud said: "I asked the Messenger of Allah (ﷺ) which action is most beloved to Allah? He said: 'Establishing prayer on time, honoring one's parents and Jihad in the cause of Allah.'"
