"Muhammad 'alaihis-salâm' was extremely beautiful-tempered, friendly, well-mannered, and utterly honest. He always avoided anger and vehemence, and was never oppressive. He asked Muslims to be always good tempered and friendly, and stated that the way to Paradise went through mildness and patience. He said that veracity, mercy, charity to the poor, hospitality, and compassion were the permanent essentials of Islam. He always lived in contentment, and avoided luxury and ostentation. He rejected all sorts of discrimination among Muslims, and showed the same respect to every Muslim. He never had recourse to coercion, unless it was inevitable, tried to settle all sorts of problems in a peaceful, placatory, admonitory and explanatory way, in which he was mostly successful. [Throughout his lifetime, he did not hurt or offend anyone. He was never angry with anyone in a matter where his own person was involved. He was never heard to say, “No,” to a request. If he had what was asked of him, he would give it; if he did not have it, the sweetness of his silence would satisfy well beyond appeasement. He was the darling of Allâhu ta’âlâ. He was the sayyid, the master of all people, past, present, and future.] In 630 he returned to Mecca, conquered the city easily, and in quite a short time transformed the semi-wild Arabs into the most civilized people of the world.
"Islam means 'to submit oneself entirely (to Allah's Will).' The Qur'ân al-kerîm is the Holy Book of the Islamic religion. Whereas in the holy books belonging to the other religions mention is made only to spiritual matters, the Qur'ân al-kerîm also contains social, economical and jurisprudential teachings. These teachings include a number of principles that people should observe in worldly life, and even several principles of civil code. In addition, it contains commandments as to how to perform acts of worship, how to fast, and how to wash, as well as admonitions that other people and votaries of other religions should be treated kindly. The Qur'ân al- kerîm commands to struggle against those non-Muslim governments that perpetrate cruelty. Its basic essential is to worship one Allah. It prohibits religious images and icons. It forbids wine and pork. It accepts Mûsâ (Moses) and Îsâ (Jesus) 'alaihimassalâm' as Prophets. Yet it holds these two Prophets inferior to the final Prophet Muhammad 'alaihissalâm'. [It is a definite fact. For the qualities and superiorities of Muhammad ‘alaihis-salâm’ are written in the Torah and in the Injîl (Bible), which were revealed to Mûsâ and Îsâ ‘alaihimassalâm’, respectively. Mûsâ and Îsâ ‘alaihimassalâm’ were aware of this fact and they therefore begged and prayed very earnestly that they be joined into his Ummat (Muslims). Îsâ’s ‘alaihis-salâm’ prayers were accepted, and Allâhu ta’âlâ raised him up to heaven, alive. Towards the end of the world he will come back down to earth, follow, and spread, the Sharî’at of Muhammad ‘alaihis-salâm’.] It gives the good news that those who accept the Islamic religion and lead a life in conformity with its commandments will go into Paradise, wherein are pleasures, rivers, fruits, and sofas covered with silk, and will be given young and beautiful houris (maidens of Paradise).
