The Most Comprehensive of Supplications – Ash-Shaykh Al-Uthaymīn
The best of supplications and most comprehensive is His statement:
وَمِنْهُم مَّن يَقُولُ رَبَّنَا آتِنَا فِي الدُّنْيَا حَسَنَةً وَفِي الْآخِرَةِ حَسَنَةً وَقِنَا عَذَابَ النَّارِ
And of them there are some who say: “Our Lord! Give us in this world that which is good and in the Hereafter that which is good, and save us from the torment of the Fire!” (Al-Baqarah: 201)
Thus, this is the most comprehensive of supplications because it combines between the good of the worldly life and the hereafter, and the Messenger of Allāh used to supplications with this a lot.
Therefore a person should supplicate with this supplication and likewise the other authentically reported supplications, so that by way of which he will be carrying out the sunnah from all angles (as is related to supplications).
