Dought & clear,- (description of the prayer) - Wording of the tashahhud and sending blessings on the Prophet (peace and blessings of Allaah be upon him).

I want to know the wording of the tashahhud in prayer, and how to send
blessings on the Prophet (peace and blessings of Allaah be upon him).
Praise be to Allaah.
The Messenger(peace and blessings of Allaah be upon him) encouraged us
to learn the rulings on prayer and how he(peace and blessings of
Allaah be upon him) prayed, so that we would follow his example in
that. He said: "Pray as you have seen me praying." Narrated by
al-Bukhaari (631).
Based on this, we must pay attention to learning this.
The wordings for the tashahhud and the blessings on the Prophet(peace
and blessings of Allaah be upon him) that have been narrated in
reports are many and various. It is best for the Muslim to recite all
of them, saying it in one form on one occasion and in another form on
another occasion, and so on, so that he will have done all the
sunnahs. He should not limit himself only to some of them. But if that
is too hard for him, then he should stick to what he is able to do,
and there is no sin on him in sha Allaah.
There follow some of the versions of the tashahhud and blessings on
the Prophet(peace and blessings of Allaah be upon him) that have been
narrated in proven reports from the Prophet(peace and blessings of
Allaah be upon him) in the prayer.
Ibn Mas'ood (may Allaah be pleased with him) recited the tashahhud as
follows:At-tahiyyaatu Lillaahi wa's-salawaatu wa't-tayyibaat,
as-salaamu 'alayka ayyuha'n-Nabiyyu wa rahmat-Allaahi wa barakaatuhu.
As-salaamu 'alayna wa 'alaa 'ibaad-Illaah is-saaliheen. Ash-hadu an
laa ilaaha ill-Allaah wa ash-hadu anna Muhammadan 'abduhu wa
rasooluhu(All compliments, prayers and pure words are due to Allaah.
Peace be upon you, O Prophet, and the mercy of Allaah and His
blessings. Peace be upon us, and on the righteous slaves of Allaah. I
bear witness that none has the right to be worshipped except Allaah,
and I bear witness that Muhammad is His slave and Messenger).
Narrated by al-Bukhaari (6265) and Muslim (402).
Ibn 'Umar (may Allaah be pleased with him) recited the tashahhud as
follows:At-tahiyyaatu Lillaahi wa's-salawaatu wa't-tayyibaat,
as-salaamu 'alayka ayyuha'n-Nabiyyu wa rahmat-Allaahi wa barakaatuhu.
As-salaamu 'alayna wa 'alaa 'ibaad-Illaah is-saaliheen. Ash-hadu an
laa ilaaha ill-Allaah wahdahu laa shareeka lah wa ash-hadu anna
Muhammadan 'abduhu wa rasooluhu(All compliments, prayers and pure
words are due to Allaah. Peace be upon you, O Prophet, and the mercy
of Allaah and His blessings. Peace be upon us, and on the righteous
slaves of Allaah. I bear witness that none has the right to be
worshipped except Allaah alone with no partner or associate, and I
bear witness that Muhammad is His slave and Messenger).

The tashahhud of 'Umar was recited by him on the minbar in order to
teach the people: "At-tahiyyaatu Lillaahi, az-zaakiyaatu Lillaahi,
al-tayyibaatu Lillaahi, al-salawaatu Lillaahi. As-salaamu 'alayka
ayyuha'n-Nabiyyu wa rahmat-Allaahi wa barakaatuhu. As-salaamu 'alayna
wa 'alaa 'ibaad-Illaah is-saaliheen. Ash-hadu an laa ilaaha ill-Allaah
wa ash-hadu anna Muhammadan 'abduhu wa rasooluhu(All compliments are
due to Allaah, all pure things are due to Allaah, all pure words are
due to Allaah, all prayers are due to Allaah. Peace be upon you, O
Prophet, and the mercy of Allaah and His blessings. Peace be upon
us,and on the righteous slaves of Allaah. I bear witness that none has
the right to be worshipped except Allaah, and I bear witness that

As for the wording of the blessings on the Prophet(peace and blessings
of Allaah be upon him), it is as follows:
"Allaahumma salli 'ala Muhammad wa 'ala aali Muhammad kama salayta
'ala Ibraaheem wa 'ala aali Ibraaheem, innaka hameedun majeed.
Allaahumma baarik 'ala Muhammad wa 'ala aali Muhammad kama baarakta
'ala Ibraaheem wa 'ala aali Ibraaheem, innaka hameedun majeed(O
Allaah, send prayers upon Muhammad and upon the family of Muhammad, as
You sent prayers upon Ibraaheem and upon the family of Ibraaheem; You
are indeed Worthy of Praise, Full of Glory. O Allaah, send blessings
upon Muhammad and upon the family of Muhammad as You sent blessings
upon Ibraaheem and upon the family of Ibraaheem; You are indeed Worthy
of Praise, Full of Glory)."
Narrated by al-Bukhaari (3370).
"Allaahumma salli 'ala Muhammad wa 'ala aali Muhammad kama salayta
'ala aali Ibraaheem, wa baarik 'ala Muhammad wa 'ala aali Muhammad
kama baarakta 'ala aali Ibraaheem fi'l-aalameen, innaka hameedun
majeed(O Allaah, send prayers upon Muhammad and the family of
Muhammad, and send blessings upon Muhammad and the family of Muhammad,
as You sent prayers and blessings upon Ibraaheem and the family of
Ibraaheem among the nations; You are indeed Worthy of Praise, Full of
Glory)."
