Abu Nadrah reported: The Messenger of Allah, peace and blessings be upon him, said:

يَا أَيُّهَا النَّاسُ أَلَا إِنَّ رَبَّكُمْ وَاحِدٌ وَإِنَّ أَبَاكُمْ وَاحِدٌ أَلَا لَا فَضْلَ لِعَرَبِيٍّ عَلَى أَعْجَمِيٍّ وَلَا لِعَجَمِيٍّ عَلَى عَرَبِيٍّ وَلَا لِأَحْمَرَ عَلَى أَسْوَدَ وَلَا أَسْوَدَ عَلَى أَحْمَرَ إِلَّا بِالتَّقْوَى أَبَلَّغْتُ

O people, your Lord is one and your father Adam is one. There is no favor of an Arab over a foreigner, nor a foreigner over an Arab, and neither white skin over black skin, nor black skin over white skin, except by righteousness. Have I not delivered the message?
