Wording Of The Tashahhud And Sending Blessings On The Prophet

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).
Narrated by Abu Dawood (971) and classed as
saheeh by al-Albaani.
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

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 sallayta ‘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 sallayta ‘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).”
