Coffee beans: A cup of coffee temporarily refreshes our mood. So what?
Chess: A good time pass, mainly for those who win the game.
Rose water and perfumes: A means of dreamy feelings.
Valve and Piston: Used in machines and cars. Machine makes life easier. Car makes journey comfortable and faster than the camel ride.
Windmill: Grinds corn, wheat to produce variety of meals.
Carpets: A sensual regal feeling.
Gun Powder: Better than sword, etc. etc.
Inventions therefore are not life’s knowledge. These are mere dexterousness for improved worldly life. This dexterity is also granted to the animals. Notice how birds create their nests and watch the migrating birds. They know when, where and how to migrate in a most disciplined optimal way. Thus both man and animal have common understanding of life’s dexterity and skills.
On the other hand, earth is given to us as trust to establish righteousness. The more the earth is permeated with justice, mercy, compassion, the nearer the earth is to the divine writ. The more corruption permeates the earth, the further away the earth from virtues. Notice that there can be no human inventions in knowledge, justice, mercy and compassion.
Next time if there is a question about Muslim inventions, in my opinion, there is no need to look into in the past.
