Vocalization markers indicating specific vowel sounds were introduced into the Arabic language by the end of the 9th century. The first Quranic manuscripts lacked these marks, therefore several recitations remain acceptable. The variation in readings of the text permitted by the nature of the defective vocalization led to an increase in the number of readings during the 10th century. The 10th-century Muslim scholar from Baghdad, Ibn Mujahid, is famous for establishing seven acceptable textual readings of the Quran. He studied various readings and their trustworthiness and chose seven 8th-century readers from the cities of Mecca, Medina, Kufa, Basra and Damascus. Ibn Mujahid did not explain why he chose seven readers, rather than six or ten, but this may be related to a prophetic tradition (Muhammad's saying) reporting that the Quran had been revealed in seven "ahruf" (meaning seven letters or modes). Today, the most popular readings are those transmitted by Hafs (d.796) and Warsh (d. 812) which are according to two of Ibn Mujahid's reciters, Aasim ibn Abi al-Najud (Kufa, d. 745) and Nafi' al-Madani (Medina, d. 785), respectively. The influential standard Quran of Cairo (1924) uses an elaborate system of modified vowel-signs and a set of additional symbols for minute details and is based on Asim's recitation, the 8th-century recitation of Kufa. This edition has become the standard for modern printings of the Quran.
Which century produced the seven readings selected by Ibn Mujahid?
8th

The speed of mail traveling between Guam and the states varies depending on size and time of year. Light, first-class items generally take less than a week to or from the mainland, but larger first-class or Priority items can take a week or two. Fourth-class mail, such as magazines, are transported by sea after reaching Hawaii. Most residents use post office boxes or private mail boxes, although residential delivery is becoming increasingly available. Incoming mail not from the Americas should be addressed to "Guam" instead of "USA" to avoid being routed the long way through the U.S. mainland and possibly charged a higher rate (especially from Asia).
Which type of service usually takes less than a week to get postage to the island?
first-class

The social identity of the children was strongly determined by the tribe's kinship system. Among the matrilineal tribes of the Southeast, the mixed-race children generally were accepted as and identified as Indian, as they gained their social status from their mother's clans and tribes, and often grew up with their mothers and their male relatives. By contrast, among the patrilineal Omaha, for example, the child of a white man and Omaha woman was considered "white"; such mixed-race children and their mothers would be protected, but the children could formally belong to the tribe as members only if adopted by a man.
What were multiracial children with a tribal mother considered to be in tribes of the Southeast?
Indian
