There are two Azhans for the Friday Prayer.
The first Azhan is recited at the
commencement of the Jum’ah (zhuhr) time
window (ie. when the sun passes the zenith
at midday )and the second adhan is recited
just before the Imam stands up to deliver his
khutbah.
The khutbah (sermon) consists of two parts:
In the first part:
The Imam begins by saying:
A`uuzhu billaahi min-ash-shaitaanir-rajeem,
Bismillaa-hir rahmaanir-raheem
Then the Imam reads the khutbah below :
Alhamdu lillaahi nahmaduhu wa nasta
‘eenuhu wa nastaghfiruhu
wa nu’ minu bihi wa natawakkalu ‘alaih.
Wa na ‘uuzhu Billaahi min shuruuri anfusinaa
wamin sayyi ‘aati a ‘maalina.
May yahdihillaahu falaa mudilla lahu
wa may yudlilhu falaa haadiya lah.
Wa nash hadu allaa ilaaha illallaahu
wahdahu laa shariika lahu
wa nash-hadu anna Muhammadan ‘abduhuu
wa Rasuuluh.
ibaadallah rahima-kumullaah.
Innallaaha ya’muru bil ‘adli wal-ihsaani wa
eetaa i zhil-qurbaa.
wa yanhaa ‘anil fahshaa i wal- munkari wal-
baghyi,
Ya ‘i zhukum la ‘allakum tazhak-karuun.
Uzhkurrullaah yazh-kur-kum
wad ‘uuhu yastajib lakum.
Wa la zhikrullaahi akbar.

(All praise is due to Allah. We laud Him, we
beseech help from Him and ask His
protection; we confide in Him, we trust Him
alone and we seek protection against the
evils and mischief of our souls and from the
bad results of our deeds.
Whomsoever He guides on the right path,
none can misguide him; and whosoever He
declares misled, none can guide him onto the
right path. And we bear witness that none
deserves to be worshipped except Allah. He
is alone and has no partner. We bear witness
that Muhammad is His servant and
Messenger. O servants of Allah! May Allah be
merciful to you.
Verily, Allah commands you to act with
justice, to confer benefits upon each other
and to do good to others as one does to one
‘s kindred and forbids evil which pertain to
your own selves and evils which affect others
and prohibits revolts against a lawful
authority. He warns you against being
unmindful.
You remember Allah; He too will remember
you; call Him and He will make a response to
your call. And verily divine remembrance is
the highest virtue.)

After delivering the first part of the sermon,
the Imam sits down for a short while, then
stands up again and starts with the second
part which reads as follows:

Alhamdu lillaahi rabbil aalameen.
Was-salaatu was-salaamu alaa rasulinaa
Muhammadin-ameen,
wa-‘alaa aalihee, wa sahbihee, aj-ma’een.
In-nallaaha wa malaa’ikata yusalluuna alan-
nabee.
Yaa ‘ay-yuhal-lazheena aamanu sallu ‘alayhi
wasallimu tasleemaa.
Allaahumma salli alaa Muhammad, wa ‘alaa
‘aali Muhammad,
kamaa sallayta alaa Ibraaheem, wa ‘alaa
‘aali Ibraaheem.
Allaa-humma baarik aala Muhammad, wa
‘alaa ‘aali Muhammad,
kama baarakta ‘alaa Ibraaheem, wa ‘alaa
‘aali ibraaheem Fil aala-meen, innaka
hameedum majeed.

(All praise is due to Allah, the Lord of all the
Worlds; may the greetings and peace be
upon the best messenger, Muhammad, and
upon his family and upon all of his
companions.
Behold, Allah and his angels shower
blessings on the Prophet. O you who believe!
Ask for blessings on him, and salute him with
a worthy greeting.
O Allah! Send your greetings upon
Muhammad and his family, just as you sent
your greetings on Abraham, and his family. O
Allah, send your blessings on Muhammad
and his family, just as you blessed Abraham
and his family. In both worlds, you are
praiseworthy and exalted.)
