The Conduct of the Prophets
قَالَ رَسُولُ اللٌّهِ )ص):أَلصَّلاَةُ مِنْ شَرَائِعِ الدِّينِ وَ فِيهَا مَرْضَاةُ الرَّبِّ عَزَّ وَ جَلَّ وَ هِيَ مِنْهَاجُ الأَنْـبِيَاءِ
The Messenger of Allah (PBUH) said: “The prayer is one of the (primary) dictates of religion, in it lies the pleasure of the Lord, the Mighty and the Glorious, and it is the conduct of the Prophets.”
