The Islamic concept of mankind's place in the universe hinges on the notion that Allah, or God, is the only true reality. There is nothing permanent other than Him. Allah is considered eternal and uncreated, whereas everything else in the universe is created. The Qur'an describes Him in Sura 112: "Say: He is Allah, Singular. Allah, the Absolute. He begetteth not nor was begotten. And to Him have never been one equal. The Qur'an condemns and mocks the pre-Islamic Arabs for attributing daughters to Allah (sura 53:19.)
Allah is considered by Muslims to be omnipotent, omnipresent, and omniscient. He is said to be "in Heaven" (Qur'an 67:16) and "in the heavens and the earth" (Qur'an 66:3), but also said to be "nearer to him [man] than his jugular vein" (Qur'an 50:16); He constantly watches all that goes on in the world, and knows all things. This suggests that He is present in the heart as the supreme witness. 'And He it is Who takes your souls at night (in sleep), and He knows what you acquire in the day, then He raises you up therein that an appointed term may be fulfilled; then to Him is your return, then He will inform you of what you were doing. (sura 6:60)'
Muslims do not try to draw or depict Allah in any way, according to Islamic belief it could lead to idol worship. Instead, they focus on His 99 attributes/names that are stated in the Quran, the holy book of the Muslims. Nearly one third of the book is used describing Allah's attributes and actions. Also, 'hadith qudsi' are special recorded sayings of Muhammad to Muslims where he quotes what Allah says to him. The ninety-nine attributes are frequently written in calligraphic Arabic as a permissible decoration, which adorns mosques and homes of Muslims.
