Narrated ‘Abdullah bin Mas’oud (radhiAllahu ‘anhu) that the Messenger of Alláh (salAllahu ‘alayhi wa sallam) taught us Khutbatul-Hajjah:
“All thanks and praises are due to Alláh, Whom we thank, seek for help and invoke for forgiveness. We seek refuge with Alláh from the evils within ourselves. He whom Alláh guides will never be misled and he whom He misguides will never find one to guide him. I bear witness that there is no deity worthy of worship except Alláh and that Muhammad is His slave and Messenger.”
He would then recite three ayaat of the Qur’an:
يأَيُّهَا الَّذِينَ ءَامَنُواْ اتَّقُواْ اللَّهَ حَقَّ تُقَاتِهِ وَلاَ تَمُوتُنَّ إِلاَّ وَأَنتُم مُّسْلِمُونَ
“O you who believe! Fear Alláh (by doing all that He has ordered and by abstaining from all that He has forbidden) as He should be feared, (obey Him, be thankful to Him, and remember Him always). And die not except in a state of Islam [as Muslims (with complete submission to Alláh].” (3: 102)
يَـأَيُّهَا النَّاسُ اتَّقُواْ رَبَّكُمُ الَّذِى خَلَقَكُمْ مِّن نَّفْسٍ وَحِدَةٍ وَخَلَقَ مِنْهَا زَوْجَهَا
“O mankind! Be dutiful to your Lord, Who created you from a single person (Adam), and from him (Adam) He created his wife [Hawwa (Eve)].” (4: 1)
يأَيُّهَا الَّذِينَ ءَامَنُواْ اتَّقُواْ اللَّهَ وَقُولُواْ قَوْلاً سَدِيداً – يُصْلِحْ لَكُمْ أَعْمَـلَكُمْ وَيَغْفِرْ لَكُمْ ذُنُوبَكُمْ وَمَن يُطِعِ اللَّهَ وَرَسُولَهُ فَقَدْ فَازَ فَوْزاً عَظِيماً
“O you who believe! Keep your duty to Alláh and fear Him, and speak (always) the truth. He will direct you to do righteous good deeds and will forgive you your sins. And whosoever obeys Alláh and His Messenger, he has indeed achieved a great achievement (i.e., he will be saved from the Hell-fire and will be admitted to Paradise).” (33:70-71)
Afterwards, he would mention whatever he wanted to speak about.
