The Messenger of Allah (may Allah's peace and blessings be upon him) taught me the Tashahhud, with my hand between his two hands, as he would teach me a Surah from the Qur’an

The Prophet (may Allah's peace and blessings be upon him) taught Ibn Mas‘ūd (may Allah be pleased with him) the Tashahhud, which is to be recited in prayer, while holding his hand between both his hands to attract his attention to him, just as he would teach him a Surah from the Qur’an. This signifies how important the Prophet regarded this Tashahhud, its words and meanings.

The Prophet (may Allah's peace and blessings be upon him) said: "At-tahiyyātu lillāh": It means that every word or deed denoting glorification is due to Allah Almighty. "As-salawāt": It means that the known prayers, both the obligatory and the voluntary, are due to Allah Almighty. "At-tayyibāt": It means that the good words, deeds, and attributes that denote perfection are all due to Allah Almighty.

"As-salāmu ‘alayka ayyuha an-nabiyyu wa rahmatullāhi wa barakātuh": A supplication for him to be granted safety from every evil and harm and to be granted more of all good things. "As-salāmu ‘alayna wa ‘ala ‘ibādillāhi as-sālihīn": It is a supplication for the one praying and for every righteous slave in heaven and on earth to be granted safety. "Ash-hadu alla ilāha illallāh": It means I firmly acknowledge that there is no true god but Allah.

"Wa anna Muhammadan ‘abduhu wa rasūluh": I affirm that he is a slave of Allah and His last Messenger. Then, the Prophet (may Allah's peace and blessing be upon him) urged the one praying to choose whatever supplication he would like.
