Abu Bekr surpassed all the Mohammedans in his austerity, his frugality,
and the simplicity of his life and outward appearance. During his rule
he wore but a single linen garment and a cloak. In this simple dress
he gave audience to the chiefs of the noblest Arab tribes and to the
kings of Yemen. The latter appeared before him dressed in richest
robes, covered with gold embroideries and wearing splendid crowns. But
at sight of the Caliph, shamed by his mingling of pious humility and
earnest gravity, they followed his example and renounced their gorgeous
attire.
