Abu 'l-Fadl Ja'far ibn Ahmad al-Mu'tadid (Arabic: أبو الفضل جعفر بن أحمد المعتضد) (895 – 31 October 932 CE), better known by his regnal name al-Muqtadir bi-Allah (Arabic: المقتدر بالله, "Mighty in God"), was the Abbasid Caliph in Baghdad from 908 to 932 CE (295-320 AH).
The death of al-Muktafi in 908 after a long illness left the issue of the succession open, and the vizier al-Abbas ibn al-Hasan al-Jarjara'i sought the advice of the most important bureaucrats on the choice of a successor. One suggestion, from Mahmud ibn Dawud, was for the experienced Abdallah ibn al-Mu'tazz, but eventually, following the advice of Ali ibn al-Furat, the vizier chose instead to confer the throne on the 13-year-old Ja'far, who was now acclaimed caliph as al-Muqtadir. The choice fell on al-Muqtadir because he was seen as weak, pliable, and easy to be manipulated by the senior officials. This was, in the words of historian Hugh N. Kennedy, "a sinister development" and inaugurated one "of the most disastrous reigns in the whole of Abbasid history [...] a quarter of a century in which all of the work of [al-Muqtadir's] predecessors would be undone".
Ahmad ibn Sulayman al-Muqtadir (or just Moctadir; Arabic: أبو جعفر أحمد "المقتدر بالله" بن سليمان, Abu Ja'far Ahmad al-Muqtadir bi-Llah ibn Sulayman) was a member of the Banu Hud family who ruled the Islamic taifa of Zaragoza, in what is now Spain, from 1049 to 1082. He was the son of the previous ruler, Al-Mustain I, Sulayman ibn Hud al-Judhami.
The 99 names of Allah (Arabic: أسماء الله الحسنى Asmāʾ Allāh al-Ḥusnā, Beautiful Names of Allah) are the names of God in Islam.Also, They are described in the Quran and Sunnah, among other places.
According to hadith there is a special group of 99 names, but no enumeration of them. Thus the exact list is not agreed upon, and the names of God (as adjectives, word constructs, or otherwise) exceed a total of 99 in the Quran and Sunnah. According to a hadith narrated by Abdullah ibn Mas'ud, some of the names of God have also been hidden from mankind.
According to Islamic tradition,Muhammad is said to have invoked God by a number of names. The most common hadith used to cite the 99 names is considered weak, though there are less commonly cited hadith which are considered authentic and also support the same point. A widely accepted hadith in Sahih Muslim states:
Over time, it became custom to recite a list of 99 names, compiled by al-Walid ibn Muslim, as an addendum to the hadith. In 2005, Mahmoud Abdel-Razek compiled an alternative list, endorsing only 69 from the al-Walid list.
