Assalamu Alaikum

This is from al adkhar of Imam nawawi

وروينا في كتاب ابن السنيّ، عن أنس رضي اللّه عنه قال‏:‏
كانَ رسولُ اللَّه صلى اللّه عليه وسلم إذا قَضى صلاتَه مسحَ جبهتَه بيده اليمنى، ثم قال‏:‏ ‏"‏أشْهَدُ أنْ لا إلهَ إِلاَّ اللَّهُ الرَّحْمَنُ الرَّحِيمُ، اللَّهُمَّ أذْهِبْ عَنِّي الهَمَّ والحزنَ‏"‏‏


To bro rqsnt, I was only passing on what I found out. When the website is up again you can read Mufti Zubair's response.

'When the Prophet[saw] finished his prayers he passed his right hand over his head and said these words:In the name of Allah besides whom there there is no other god,the kind,the merciful.O Allah drive away from me worries and grief'' [At tabaraani#451]
