they [non-Muslim Europeans, Americans, etc] dont even know that much of the Rahma [blessings and good things] that they have now is a result of his [the Prophet Muhammad's pbuh] Ummah, the medicine that they have is a result of his ummah, the universities they have are a result of his ummah, the fact that they enjoy gardens is a result of his ummah, the fact that they enjoy much of the modern things that have made their lives easier is a result of his ummah because they [the Muslims] took the word iqra ['read'; the first word that was revealed of the Quran] seriously and they studied and they transferred their knowledge to the Europeans and it was with the knowledge of this ummah that they achieved what they achieved,
they dont realise that much of what they have is a result of the Rahma of the Prophet [saw]; they were barbarians before the muslims, they didn't even wash; the Eurpoeans used to put oranges, they wore oranges with cloves stuffed to get rid of the stench because the christians thought that to take care of the body was a bad thing until the muslims taught them about the hammam [baths]; thats where they took it from because the Hammam is from the muslims; they wouldn't even have a bath, they woudln't even have a basin, if it wasn't for the Rahma of this ummah...'
Ref: now deleted Shaykh Hamza Yusuf video
Yes, everything in this World happens as Allah had willed. Even the world wars , It means If Allah wanted to stop it they could have never happened . But Allah allowed it happened to Prove & show who are the evil doers and who are the right ones , the goer's of Hell & heaven (paradise)
All advancement in the world is also ONLY through Allah's given brains and consequent knowledge (according to the attempts made by some and as per the needs of their times & Allah bestows those Successes as Allah wills ) Muslims were THE origins of researchers on various fields but after Crusades the crusaders snatched them away from Muslims and developed them further untill now .
