Sulayman ibn Rabi'a al-Bahili

Sulayman ibn Rabi'a al-Bahili used to breed and to Arabize horses in the time of Umar ibn al-Khattab (may God be pleased with him), that is, to distinguish the hybrid from the purebred among them ².

Amr ibn Ma'd Yakrib came to him with a bay horse, and he recorded it as a hybrid, so Amr called Umar as a witness against him. Sulayman ordered a short-walled, shaking vessel to be filled with water. A purebred horse was brought, and it hastened, lowered its hoof, stretched its neck and drank. Then Amr's horse was brought; it hastened and did as the purebred had done, then bent one of its hooves slightly and drank. Umar said: "You are Sulayman of the horses" ².
