Salam,
Bismillah.
Bismillah.
Narrated 'Itban bin Malik:
We prayed with the Prophet and used to finish our prayer with the Taslim along with him.
Hadith no. 801 is a repeat. Read it here.
Narrated Abu Ma'bad (the freed slave of Ibn 'Abbas):
Ibn 'Abbas told me, "In the lifetime of the Prophet it was the custom to celebrate Allah's praises aloud after the compulsory congregational prayers." Ibn 'Abbas further said, "When I heard the Dhikr, I would learn that the compulsory congregational prayer had ended."
Narrated Ibn 'Abbas:
I used to recognize the completion of the prayer of the Prophet by hearing Takbir.
Sunnah: say 'Allahu Akbar' loudly after finishing your compulsory (fardh) Salah.
There's lots of other adhkaar we find in Sunnah that Prophet (SAW) used to do after finishing his fardh Salah. Some of them will be posted in the following days inshaAllah.
Wassalam.
