We touch on this issue and talk about the following hadeeth:

Abu Nadrah reported: The Messenger of Allah, peace and blessings be upon him, said during the middle of the day at the end of the pilgrimage, “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/red skin over black skin, nor black skin over white/red skin, except by righteousness. Have I not delivered the message?” They said, “The Messenger of Allah has delivered the message.”  Source:

 عَنْ أَبِي نَضْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي وَسَطِ أَيَّامِ التَّشْرِيقِ فَقَالَ 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 قَالُوا بَلَّغَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ
