Hadith: No racial superiority, only piety makes someone superior
It is reported that the Prophet ﷺ said:
O people! You all share one God and one father.
An Arab is no better than a non-Arab, and a non-Arab is no better than an Arab.
Whites are not superior to blacks, nor are blacks superior to whites. Only piety makes one person better than another.
In Arabic:
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 ؟
Notes
This hadith is in the Musnad of Ahmad ibn Hanbal.
According to the beginning of the report, this statement was made during a sermon (khutba), which is remarkable to imagine.
