ذِكْرُ الْبَيَانِ بِأَنَّ الصَّلَاةَ لِوَقْتِهَا مِنْ أَفْضَلِ الْأَعْمَالِ
Prayer at its appointed hour. I (again) said: Then what? He (the Holy Prophet) replied: Kindness to the parents. I (again) said: Then what? He replied: Earnest endeavour (Jihad) in the cause of Allah. And I would have not ceased asking more questions but out of regard (for his feelings). (Using translation from Muslim 85a)
سَأَلْتُ النَّبِيَّ ﷺ أَيُّ الْعَمَلِ أَفْضَلُ؟ قَالَ «الصَّلَاةُ لِوَقْتِهَا»
