Mohammad (pbuh) the liberator
We can call Prophet Mohammad (pbuh) a liberator of all humanity if we follow his teachings, not so much from the tangled web of Hadith but from the Quran that he brought us. The Quran indeed was his real miracle. Firstly, he emphasized the importance of knowledge. This word occurs in the Quran more than 800 times along with its various derivatives (the word jihad, so controversial today, occurs only 41 times).
Knowledge was so important to him that he required Muslims to seek knowledge even if they had to go to China, then a very distant land from Arabia. Following this teaching, Arabs who were quite averse to knowledge — especially in the written form (there were only 17 people in Makkah during the Prophet’s lifetime who could read and write) — became great precursors of various sciences and even the West immensely benefited from their findings. The West discovered the treasures of Greek knowledge through the Arabs.
