There is an anecdote told of Mohammed, the prophet of Islam.
One day, a panting dog feebly approached one of his followers, who took notice of the poor animal. Seeing a puddle of muddy water, he tore a scrap off the hem of his shirt, soaked it in the water and taking the dog in his lap, he moistened its mouth.
Another person, witnessing this, went and told the Prophet that a member of the group had handled a filthy animal, "and therefore he should not be allowed back here again."
Mohammed asked, "What was he doing to the dog ?"
"I don't know, but I saw him moistening its mouth with a torn piece of cloth dipped in muddy water."
"Then," replied the Prophet, "He is a better Muslim than you, because he is kind to animals."
