This was the start of—or perhaps a subsequent means of justifying—Khwaja Khizr's ubiquity in the Islamic world. Richard Carnac Temple, a civil servant in 19th century British Sindh, researched, but never published, a monograph of the saint, entitled Zinda Peer Everliving Saint of India. Khwaja Khizr, he wrote, is "known to every child from Morocco to the Malay Peninsula, the helper in all trouble of whatever kind, and at the same time the bogie par excellence, and the most widely known of all the modern sea and river godlings or saints." In Muslim versions of the Alexander Romance—the medieval legends of Alexander the Great, popular in Europe and Asia—Khwaja Khizr became the eponymous hero's friend, accompanying him on a quest for the Fountain of Eternal Life. This, Khizr discovered by chance when a dried fish he was carrying fell into a spring and he watched amazed as his lunch flicked its fins and swam away. Khizr drank deeply from the spring, and hurried away to fetch Alexander, but by the time they returned the spring had disappeared (luckily for mankind, or else Alexander would even to this day be marching round the world, conquering random countries according to his whim). Instead, it is the "shy and retiring" Khwaja Khizr who lives on. The patron of travellers, the helper of those in dire need, he manifests himself to those who call upon him in sincerity.
His first recorded appearance in Sindh occurred in 952 CE, when a Delhi merchant was sailing down the river with his daughter, a girl whose uncommon loveliness came to the attention of the local Hindu raja. The wicked man attempted to ravish her, but the girl called upon Khwaja Khizr, who diverted the Indus from flowing past the raja's capital at Alor, and instead landed the boat safely on the island in the river. (The current Sajjada Nasheen, who has spent his life working for Pakistan's infamous, all-powerful Water And Power Development Authority [WAPDA], feels duty-bound to point out to me that while it is true that the Indus changed course several centuries ago, as an engineer he is unable to confirm that this occurrence was Khwaja Khizr's own creation. Even Quranic prophets who have drunk deeply from the elixir of eternal youth have their limits.)
