صَحِيحُ مُسْلِمٍ
Sahih Muslim 592 b
The Book of Mosques and Places of Prayer
It is recommended to recite statements of remembrance after the prayer, and how that is to be done
وَحَدَّثَنَاهُ ابْنُ نُمَيْرٍ، حَدَّثَنَا أَبُو خَالِدٍ، - يَعْنِي الأَحْمَرَ - عَنْ عَاصِمٍ، بِهَذَا الإِسْنَادِ وَقَالَ يَا ذَا الْجَلاَلِ وَالإِكْرَامِ .
Ibn Numair narrated it with the same chain of transmitters and said: O Possessor of Glory and Honour.
