Ibn ‘Umar (may Allah be pleased with him) reported:
The Messenger of Allah (may Allah's peace and blessings be upon him) delivered a speech on the day of the Conquest of Makkah. He said: "O people, verily Allah has removed the arrogance of jāhiliyyah from you and their boastfulness about their forefathers. So, now, there are two types of men: a righteous, pious, and honorable person in the sight of Allah and a wicked, wretched, and insignificant person in the sight of Allah. People are the children of Adam, and Allah created Adam from dust. Allah says: {O mankind, We have created you from a male and a female, and made you into nations and tribes so that you may recognize one another. Indeed, the most noble of you before Allah is the most righteous among you. Indeed, Allah is All-Knowing and all-aware.} [Surat al-Hujurāt: 13]"
The Prophet (may Allah's peace and blessings be upon him) delivered a speech on the day of the Conquest of Makkah, saying: O people, indeed Allah removed from you the arrogance and fanaticism of jāhiliyyah and the boastfulness about one's ancestors. People are of two types:
Either a believer who is pious, righteous, and obedient to Allah Almighty - and this is honorable in the sight of Allah, even if he does not occupy high status among the people.
Or a disbeliever who is wicked and wretched - and this is insignificant and worthless in the sight of Allah, even if he occupies a high status, strong position and authority.
People are the children of Adam, and Allah created Adam from dust. Allah says: {O mankind, We have created you from a male and a female, and made you into nations and tribes so that you may recognize one another. Indeed, the most noble of you before Allah is the most righteous among you. Indeed, Allah is All-Knowing and all-aware.} [Surat al-Hujurāt: 13]"

Explanation in Arabic
خَطَبَ النبيُّ صلى الله عليه وسلم الناس يومَ فتحِ مكة فقال: يا أيها الناس إن الله قد رفع وأزال عنكم كِبْرَ الجاهليةِ ونَخْوَتَها، والفخرَ بالآباء، وإنما الناس على نوعين:
إما مؤمنٌ بَرٌّ تقيٌّ طائعٌ عابدٌ لله عزوجل، فهذا كريمٌ على الله، وإنْ لم يكن ذا حَسَبٍ أو نَسَبٍ عند الناس.
وإما كافرٌ فاجرٌ شقيٌّ، وهذا هيِّنٌ ذليل على الله، ولا يساوي شيئًا، وإنْ كان ذا حَسَبٍ وله جاه وسلطان.
والناس كلُّهم أبناء آدم، وخلقَ اللهُ آدمَ من التراب، فلا يليق بمن أصله من تراب أن يتكبَّرَ ويُعْجَبَ بنفسه، ومصداق ذلك قول الله عز وجل: {يا أيها الناس إنا خلقناكم من ذكر وأنثى وجعلناكم شعوبا وقبائل لتعارفوا إن أكرمكم عند الله أتقاكم إن الله عليم خبير} [الحجرات: 13].
