It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that when the Noble Prophet (peace and blessings be upon him) would sit at the end of the prayer (for Tashahhud), he would place his left hand on his left knee and his right hand on his right knee, and he would keep his finger raised.

Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: When we used to pray behind the Messenger of Allah (peace and blessings be upon him), we would say: Peace be upon Allah before His servants, peace be upon Jibreel and Mika'il, peace be upon Israfil, peace be upon so-and-so and so-and-so. Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said: Then the Messenger of Allah (peace and blessings be upon him) turned towards us and said: "Allah Himself is As-Salam (the Source of Peace), (so why do you send peace upon Him?), when you sit in prayer (for Tashahhud), then say: «التحيات لله ........... إلى وعلی عباد الله الصالحين» meaning: 'All verbal and physical acts of worship (or all words of respect and glorification), all acts of worship (prayers, etc.), and all the best praises and charities are for Allah alone. Peace be upon you, O Prophet, and the mercy of Allah and His blessings. Peace be upon us and upon all the righteous servants of Allah.' When you say this, your greeting will reach every righteous servant of Allah in the heavens and the earth, wherever they may be. I bear witness that there is no deity except Allah, and I bear witness that Muhammad is His servant and Messenger. Then after this, let him supplicate for whatever he wishes."

Qasim bin Mukhaimara narrated that Alqama held my hand and narrated a hadith to me that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) held his hand and said that the Messenger of Allah (peace and blessings be upon him) held Abdullah's hand and taught him how to recite the Tashahhud in prayer, and «(اَلتَّحِيَّاتُ لِلّٰهِ وَالصَّلَوَاتُ وَالطَّيِّبَاتُ ........... إِلَى الصَّالِحِيْن)» Zuhair said: I think he made him memorize it up to «‏‏‏‏أَشْهَدُ أَنْ لَا إِلٰهَ إِلَّا اللّٰهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُوْلُهُ» ‏‏‏‏, he became doubtful in the two testimonies. Then he said: When you have done or said so, then complete your prayer, and if you wish to stand up, then stand up, and if you wish to remain seated, then remain seated.

Ibn Abi Layla says: I met Sayyiduna Ka'b bin Ujrah (may Allah be pleased with him), and he said: Shall I not give you a gift? The Messenger of Allah (peace and blessings be upon him) came to us, so we said: We have learned how to send peace upon you, but how should we send blessings (salat) upon you? He said: Say like this «(اللّٰهُمَّ صَلِّ عَلَىٰ مُحَمَّدٍ ...... إِنَّكَ حَمِيْدٌ مَجِيْدٌ)» "O Allah! Have mercy and grace upon Muhammad and the family of Muhammad as You had mercy and grace upon Ibrahim. Surely, You are Praiseworthy and Glorious. O Allah! Bless Muhammad and the family of Muhammad as You blessed Ibrahim. Surely, You are Praiseworthy and Glorious."

Naeem Mujmir narrates from the freed slave of Sayyiduna Umar bin Al-Khattab (may Allah be pleased with him) that Muhammad bin Abdullah bin Zaid Al-Ansari, who saw the dream of giving the Adhan during the time of the Messenger of Allah (peace and blessings be upon him) (the dream was seen by his father Abdullah as mentioned earlier and as in Muslim), informed that Sayyiduna Abu Mas’ud Al-Ansari Uqbah bin Amir (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) came to us and sat with us in the gathering of Sa’d bin Ubadah. Basheer bin Sa’d, who is Abu Nu’man bin Basheer, said to him: O Messenger of Allah! Allah Almighty has commanded us to send blessings upon you, so how should we send blessings upon you? He replied:“Say like this: «اللّٰهُمَّ صَلِّ عَلَى مُحَمَّدٍ وَعَلىٰ آلِ مُحَمَّدٍ كَمَا صَلَّيْتَ عَلَى إِبْرَاهِيْمَ وَبَارِكْ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ كَمَا بَارَكْتَ عَلَى آلِ إِبْرَاهِيْمَ فِي الْعَالَمِيْنَ إِنَّكَ حَمِيْدٌ مَجِيْدٌ» and as for the way of greeting (salaam), you already know it.”

Abu Huraira (may Allah be pleased with him) reports: The Messenger of Allah (peace and blessings be upon him) said: "When any of you finishes the Tashahhud, let him seek refuge with Allah from four things: from the punishment of Hell, from the punishment of the grave, from the trials of life and death, and from the trial of the False Messiah (Al-Masih ad-Dajjal)."

It is also narrated in the same way from Awza'i.

Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) said: When the Messenger of Allah (peace and blessings of Allah be upon him) turned to the right to say salam, the whiteness of his cheek would become visible, then when he turned to the left to say salam, the whiteness of his (left) cheek would become visible.

Abu Ma'mar said: In Mecca, I prayed behind a man and he turned his head to both sides (for salam). I mentioned this to Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him), so he said: From where did he get this (Sunnah)? And Hakam said: The Noble Prophet (peace and blessings be upon him) used to do the same.

Lady Aisha (may Allah be pleased with her) said: The Noble Prophet (peace and blessings be upon him) used to sit after the prayer for only as long as this: «اَللّٰهُمَّ أَنْتَ السَّلَامُ وَمِنْكَ السَّلَامُ تَبَارَكْتَ يَا ذَالْجَلَالِ وَالْإِكْرَامِ» .
