Which deed is dearest to Allah? He said: "Offering prayer at its earliest appointed time." I said: Then, what comes next? He said: "Dutifulness to one's parents." I said: Then, what comes next? He said: "Jihad in the way of Allah

عَنْ عَبْدِ اللَّهِ بِن مَسْعُودٍ رضي الله عنه قَالَ: سَأَلْتُ النَّبِيَّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ: أَيُّ العَمَلِ أَحَبُّ إِلَى اللَّهِ؟ قَالَ: «الصَّلاَةُ عَلَى وَقْتِهَا»، قَالَ: ثُمَّ أَيٌّ؟ قَالَ: «ثُمَّ بِرُّ الوَالِدَيْنِ» قَالَ: ثُمَّ أَيٌّ؟ قَالَ: «الجِهَادُ فِي سَبِيلِ اللَّهِ» قَالَ: حَدَّثَنِي بِهِنَّ، وَلَوِ اسْتَزَدْتُهُ لَزَادَنِي.

‘Abdullah ibn Mas‘ūd (may Allah be pleased with him) reported: I asked the Prophet (may Allah's peace and blessings be upon him): Which deed is dearest to Allah? He said: "Offering prayer at its earliest appointed time." I said: Then, what comes next? He said: "Dutifulness to one's parents." I said: Then, what comes next? He said: "Jihad in the way of Allah." He said: These were the things he said to me, and if I had asked him for more, he would have given me more.
