A Mohammedan youth, Hakim Alí by name, on his return from a journey through Arabia, visited his friend Yuhanna, the Christian. Though the two held not the same faith, there was much friendship between them.[49] They sat together under a pépul tree, and Hakim Alí, with great animation, gave to Yuhanna an account of all that he had seen in his travels. For a long time Yuhanna had all the listening, and his friend had all the talking. In almost every sentence uttered by Hakim Alí, he brought in the name of Allah (God); if he were but describing how a mule stumbled, or what evil fare he had had at an inn, he called God to bear witness to what he said—even if he were laughing when the holy name was on his lips. Yuhanna had a stick in his hand, and every time that Hakim Alí uttered the sacred name, Yuhanna with the stick made a mark on the sand. Hakim Alí at last noticed with surprise this act of Yuhanna.
