The sermon of the Holy Prophet sallallahu alayhi wasallam on the day of Hajja-tul-Widaa

The Holy Prophet Muhammad sallallahu alayhi wasallam said in his sermon of Hajja-tul-Widaa.
"O people! listen to my words, for I do not know whether we shall ever meet again in this place and perform Hajj after this year. O people! Allah says:- 'O people! We created you from one male and one female and made you into tribes and nations, that you may know each other (not that you may despise each other). Verily the most honored of you in the sight of Allah is (he who is) the most righteous of you.' There is no superiority for an Arab over a non-Arab and for a non-Arab over an Arab, nor for the white over the black nor for the black over the white except through Taqwaa (God-fearing)."
Further more he said:
"O people! there is no prophet after me and no new Ummah (would be formed) after you."
Then he said:
"Behold, worship your Lord; offer prayers five times a day; observe fast in the month of Ramadhaan; pay the Zakaat of your wealth happily; and perform pilgrimage to the House of your Lord and obey your rulers and you will enter the Paradise of your Lord.
Let him that is present, convey it to the one who is absent. For many people to whom the message is conveyed may be more mindful of it than the audience."

Then the Prophet sallallahu alayhi wasallam asked,
"And you will be asked about me (in the Hereafter), What will you say?"
The Sahaabah radhiyallahu auhum replied,
"We bear witness that you have conveyed the trust (of religion) and proclaimed the mission (Apostle-ship) and looked after our welfare."
Thereupon, Allah's Messenger sallallahu alayhi wasallam lifted his fore finger towards the sky and then pointing towards the people, he said:
"O Allah!Bear witness unto it. O Allah! Bear witness unto it."
