Sahih al-Bukhari, Hadith 2782 ⓘ
Narrated `Abdullah bin Masud: I asked Allah's Messenger, "O Allah's Messenger! What is the best deed?" He replied, "To offer the prayers at their early stated fixed times." I asked, "What is next in goodness?" He replied, "To be good and dutiful to your parents." I further asked, what is next in goodness?" He replied, "To participate in Jihad in Allah's Cause." I did not ask Allah's Messenger anymore and if I had asked him more, he would have told me more.
حَدَّثَنَا الْحَسَنُ بْنُ صَبَّاحٍ، حَدَّثَنَا مُحَمَّدُ بْنُ سَابِقٍ، حَدَّثَنَا مَالِكُ بْنُ مِغْوَلٍ، قَالَ سَمِعْتُ الْوَلِيدَ بْنَ الْعَيْزَارِ، ذَكَرَ عَنْ أَبِي عَمْرٍو الشَّيْبَانِيِّ، قَالَ قَالَ عَبْدُ اللَّهِ بْنُ مَسْعُودٍ ـ رضى الله عنه ـ سَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم قُلْتُ يَا رَسُولَ اللَّهِ أَىُّ الْعَمَلِ أَفْضَلُ قَالَ " الصَّلاَةُ عَلَى مِيقَاتِهَا ". قُلْتُ ثُمَّ أَىٌّ. قَالَ " ثُمَّ بِرُّ الْوَالِدَيْنِ ". قُلْتُ ثُمَّ أَىٌّ قَالَ " الْجِهَادُ فِي سَبِيلِ اللَّهِ ". فَسَكَتُّ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم وَلَوِ اسْتَزَدْتُهُ لَزَادَنِي.
