Allah created Adam from a handful which he took from the whole of the earth ; so the children of Adam are in accordance with the earth : some red, some white, some black, some a mixture, also smooth and rough, bad and good. (Using translation from Abū Dāʾūd 4693)
عَنِ النَّبِيِّ ﷺ وحَدَّثَنَاهُ هَوْذَةُ حَدَّثَنَا عَوْفٌ عَنْ قَسَامَةَ قَالَ سَمِعْتُ الْأَشْعَرِيَّ يَقُولُ قَالَ رَسُولُ اللهِ ﷺ إِنَّ اللهَ ﷻ خَلَقَ آدَمَ مِنْ قَبْضَةٍ قَبَضَهَا مِنْ جَمِيعِ الْأَرْضِ فَجَاءَ بَنُو آدَمَ عَلَى قَدْرِ الْأَرْضِ جَاءَ مِنْهُمْ الْأَحْمَرَ وَالْأَبْيَضَ وَالْأَسْوَدَ وَبَيْنَ ذَلِكَ وَالسَّهْلَ وَالْحَزْنَ وَبَيْنَ ذَلِكَ وَالْخَبِيثَ وَالطَّيِّبَ وَبَيْنَ ذَلِكَ
