KHUTBAH AL HAAJAH
Khutbah is an Arabic word, in English it is referred as SERMON. Khutbah pertains to speaking to an audience for the purpose of conveying the message. And a Khutbah is given generally on Friday and before Marriage. Khutbah al-Haajahis the same as Khutbah al-Nikaah meaning the wordings are same for both, which the Prophet (peace and blessings of Allaah be upon him) taught his Companions, and it should be said at the beginning of the Friday Sermon or the Nikah Sermon.
The Khutbah is one of the great symbols of Islam and an act of worship legislated, ordained and practiced by the Messenger of Alláh and the Rightly Guided Caliphs after him. Ever since, the Muslim Ummah has kept this tradition seeking to raise Alláh's remembrance high, honoring His Symbols and Limits, calling to His Path and warning against defying His Commandments. 
Innal hamda Lillaahi nahmaduhu wa nasta’eenahu wa nastaghfiruhu, wa na’oodhu billaahi min shuroori anfusinaa wa sayi’aati a’maalinaa. Man-yahdih Illaahu falaa mudilla lahu wa man yudlil falaa haadiya lahu. Wa ashhadu an laa ilaaha ill-Allaah wa ashhadu anna Muhammadan ‘abduhu wa rasooluhu . Meaning is Praise be to Allaah, we seek His help and His forgiveness. We seek refuge with Allaah from the evil of our own souls and from our bad deeds. Whomsoever Allaah guides will never be led astray, and whomsoever Allaah leaves astray, no one can guide. I bear witness that there is no god but Allaah, and I bear witness that Muhammad is His slave and Messenger. Sunan an-Nasa'i Vol 4:3278
Then the following three aayaat are recited: ‘Yaa ayyuha’lladheena aamanu-ttaqu’Llaaha haqqa tuqaatihi wa laa tamootunna illaa wa antum muslimoon (O you who believe! Fear Allaah as He should be feared, and die not except in a state of Islam (as Muslims) with complete submission to Allaah.)’ [Qur’an Surah A’al ‘Imran 3:102], ‘Yaa ayyuha’n-naas uttaqu rabbakum alladhi khalaqakum min nafsin waahidatin wa khalaqa minhaa zawjahaa wa baththa minhumaa rijaalan katheeran wa nisaa’an wa’ttaqu-Llaah alladhi tasaa’aloona bihi wa’l-arhaama inna Allaaha kaana ‘alaykum raqeeban (O mankind! Be dutiful to your Lord, Who created you from a single person, and from him He created his wife, and from them both He created many men and women, and fear Allaah through Whom you demand your mutual (rights), and (do not cut the relations of) the wombs (kinship) Surely, Allaah is Ever an All-Watcher over you).’ [Qur’an surah al-Nisaa’ 4:1], ‘Yaa ayyahu’lladheena aamanu-ttaqu’Llaaha wa qooloo qawlan sadeedan (O you who believe! Keep your duty to Allaah and fear Him, and speak (always) the truth).’ [Qur’an surah al-Ahzaab 33:70].”
