وَاللَّهِ لَئِنْ بَقِيتُ لَيَأْتِيَنَّ الرَّاعِي بِجَبَلِ صَنْعَاءَ حَظُّهُ مِنْ هَذَا الْمَالِ
If God grants me life, I shall see to it that even the lonely shepherd in the mountains of San’a shall have his share in the wealth of the community.
—The Second Caliph ‘Umar ibn al-Khaṭṭāb [d. 23H/644CE]
