The mother, having no nipples, nurses the young with milk that comes directly from her belly skin. In about four months, the young emerge for the first time from the burrow, each about a foot long and with a full coat of fur.

Imam al-Baqir (PBUH) said: Verily, Allah, the exalted, has put some locks on vices, the key of which He has put in wine, but the vice of lying is worse than wine.

In the platypus, the combined abilities of electroreception and mechanoreception are so sensitive and detailed that they have become something like vision, providing a three-dimensional "view" of the platypus underwater world, and enabling the platypus to pinpoint, in all three dimensions, the exact locations of its prey.

Once Imam Ali (PBUH) was asked about the distance between the truth and untruth and, while he was showing the distance between his eye and ear with his four fingers in order to illustrate this distance as his answer, he said: What your eyes see is truth and what your ears hear is for the most part untruth.

Imam Sajjad (PBUH) said: Avoid telling lies irrespective of small or great, whether it is in earnest or joking, because when a person tells a lie in small (things), he dares to tell a lie in great things, too.

In addition to detecting bursts of electricity from prey animals, the electroreceptors in a platypus bill can probably detect the tiny electric currents made by water flowing over and around rocks and sunken logs, thus producing a three-dimensional map of a river or lake bottom within the platypus brain.

These detect tiny, underwater bursts of electricity from the muscles of swimming creatures that the platypus hunts. The electroreceptors are intermingled with 60,000 mechanoreceptors, nerves ending at the skin in tiny "push rods" that respond to small pressure changes and detect the movements of prey animals underwater and on the bottoms of streams and ponds. Together, the two senses allow the platypus to home in on prey.

Imam Kazim (PBUH) said: Cursed is the one who backbites against ones brother (fellow Muslim).

The monotremes, the echidnas and platypus, are the only living mammals that are known to have an ability to sense electricity. The platypus bill is something unique in nature, so sophisticated and advanced that no one can call the platypus "primitive." The skin surface of the bill contains 40,000 tiny electroreceptors, or specialized sensory nerve endings, arranged in rows along the length of the bill.
