In Fariduddin Attar's 'Elahi Nameh' (The Book of God), the tale of the praying man and the dog serves as a profound allegory criticizing spiritual hypocrisy and ostentation (riya). A seemingly devout man spends the entire night in a dark mosque praying with exaggerated fervor because he hears footsteps, assuming a holy person has entered and is watching him. At dawn, he discovers that his observer was merely a stray dog seeking shelter. Attar uses this story to highlight the folly and emptiness of performing acts of worship to seek validation from others rather than dedicating them sincerely to God. The man's profound embarrassment upon realizing he spent the night showing off for a dog underscores the Sufi teaching that true devotion must be internally pure and free from the desire for worldly approval.
