Whenever one wants to pick up something...
Whenever one wants to pick up something, it is only this fingernail, which enables the fingers to bear the pressure. Otherwise it was not possible to bear such crushing weight for the fleshy fingers. That is why; if nails are drawn out from their base it will be difficult to lift things. What would then have happened had there been no nails at all? Moreover, these nails help us in scratching. Again, dirty and excessive matters within the body also go out through these nails.
That is why it has been ordered that nails must be cut at least once a week (specially on Friday). Exit of Excessive Matter through Hair Not a single strand of hair on our body is without wisdom or strategy. Imam Sadiq (a.s) tells Mufaddal Ibne Umar, “Some ignorant people say it would have been better were hair not to grow on certain parts of the body. They do not know that those are the parts where excess and dirty (impure or unclean) body matter concentrates.
Was that dirt not to be driven out through hair human body would become ill and diseased.”[^1] That is why we have been commanded to remove this hair as soon as possible (within two weeks at the most). If man ponders deeply he will realize that all the elements of the world of creation are full of wisdom and strategy.
Medicine from Cow dung Beetle Proved Effective for Eye Trouble It is said that the famous physician Galen once looked at the dirty insect cow dung beetle and expressed his opinion saying, “I do not see any wisdom in the creation of this thing. Why, after all, had God created it?” After sometime he developed severe pain in his eyes. Despite using all medicines in his expert knowledge no remedy worked on that trouble. Other doctors also tried in vain.
At last there came an old woman and said, “I have a pill. It is very effective for the illness of eyes.” When Galen used it, he became all right. He asked how the pill was prepared. She said it was a paste having cow dung beetle as one of its ingredients. Is the World's Existence Void of Wisdom? Not even a single particle in the world of existence is created without any wise aim. Can then the entire universe be aimless at all? In the human body, even a nail and a hair are not without utility.
Can then the whole human body have been created without any aim or intention? Never! All modern day scientists are unanimous in their opinion that they have not been able to comprehend all the wisdoms and strategies behind all the things in this world.
