Yahya ibn Umar was killed in a battle in 1057, but Abdullah ibn Yasin, whose influence as a religious teacher was paramount, named his brother Abu Bakr ibn Umar as chief.

They were, however, completely conquered by Abu Bakr ibn Umar, and adopted Islam as a religion.

Abu Bakr married a noble and wealthy woman, Zaynab an-Nafzawiyyat, that would become very influential in the development of the dynasty.

In 1061, Abu Bakr ibn Umar made a division of the power he had established, handing over the more-settled parts to his cousin Yusuf ibn Tashfin, as viceroy, resigning to him also his favourite wife Zainab.

In November 1087, Abu Bakr was killed in battle by a poisoned arrow, while fighting in the historic region of the Sudan.

* Abu Bakr ibn Umar ( 1056 – 1087 )-partitioned reign from 1072.

Abu Bakr ( Abdullah ibn Abi Quhafa ) (, c. 573 CE – 23 August 634 CE ) also known as Abū Bakr as-Șiddīq ( Arabic: أبو بكر الصديق ) was a senior companion ( Sahabi ) and the father-in-law of the Islamic prophet Muhammad.

As Caliph, Abu Bakr succeeded to the political and administrative functions previously exercised by Muhammad, since the religious function and authority of prophethood ended with Muhammad's death according to Islam.

As a young man, Abu Bakr became a cloth merchant and he traveled extensively in Arabia and neighboring lands in the Middle East, through which he gained both wealth and experience.

Not long after, Abu Bakr accepted Islam and was the first person outside the family of Muhammad to openly become a Muslim.

Abu Bakr served as a trusted advisor and close friend to Muhammad.

Muhammad later reaffirmed this title when he said that Abu Bakr is the ' atiqe ' ( the one saved from hell fire by God ).

Imam Jafar al Sadiq famously narrated how the title Siddiq was given to Abu Bakr from Muhammad.

He was also a direct descendant of Abu Bakr from his maternal side, as well as being a paternal descendant of Ali from his father's side.

Jafar al-Sadiq was also the successor of the Naqshbandi Sufi order originating from Abu Bakr himself.

Imam Muhammad al Baqir, the father of Imam Jafar Sadiq also called Abu Bakr with the title Siddiq.

Abu Bakr was born in Mecca some time in 573 CE, to a rich family in the Banu Taym clan of the Quraysh tribe.

The lineage of Abu Bakr joined that of Muhammad in the eighth degree in their common ancestor Murrah ibn Ka ' b.

The lineage of Abu Bakr was: Abu Bakr ; the son of Uthman Abu Quhafa ; the son of Amar ; the son of Umru ; the son of Kaab ; the son of Saad ; the son of Taym ; the son of Murrah.

Around 1035, the Lamtuna chieftain Abu Abdallah Muhammad ibn Tifat ( alias Tarsina ), tried to reunite the Sanhaja desert tribes, but his reign lasted less than three years.

He was instrumental in the conversion of many people to the Islamic faith and early in 623, Abu Bakr's daughter Aisha was married to Muhammad, strengthening the ties between the two men.

Tabari, the most famous Muslim historian, in his Ta ' rikh quotes from Muhammad Bin Sa ' ad Bin Abi Waqqas, who said: " I asked my father whether Abu Bakr was the first of the Muslims.

Dubbed " Abu Hashim ", Nami was considered " gentle in manner " by his colleagues, and reported that he had a dream in which he rode a mare along with Muhammad, and that the prophet told him to dismount and fight his enemies to liberate his land.

Abu Bakr was elected as the first caliph or successor to Muhammad, with the other companions of Muhammad giving an oath of allegiance to him.

* Abu Hurairah reported that Muhammad said: " If you survive for a time you would certainly see people who would have whips in their hands like the tail of an ox.

* Abu Hurairah narrated that Muhammad said, " When honesty is lost, then wait for the Day of Judgment.

* 1374-Following a period of internal instability in the Marinid Sultanate of Fez, Abu al-Abbas Ahmad of Fez, ask for Muhammad V of Granada help.

An example of a Hadith Qudsi is the hadith of Abu Hurairah who said that Muhammad said:

Narrators who took the side of Abu Bakr and Umar rather than Ali, in the disputes over leadership that followed the death of Muhammad, are seen as unreliable by the Shia ; narrations sourced to Ali and the family of Muhammad, and to their supporters, are preferred.

The earliest comprehensive work in hadith studies was Abu Muhammad al-Ramahurmuzi's al-Muhaddith al-Fasil, while another significant work was al-Hakim al-Naysaburi's Ma ‘ rifat ‘ ulum al-hadith.

Nasir ud-din Muhammad Humayun (; full title: Al-Sultan al -' Azam wal Khaqan al-Mukarram, Jam-i-Sultanat-i-haqiqi wa Majazi, Sayyid al-Salatin, Abu ' l Muzaffar Nasir ud-din Muhammad Humayun Padshah Ghazi, Zillu ' llah ; OS 7 March 1508 – OS 17 January 1556 ) was the second Mughal Emperor who ruled present day Afghanistan, Pakistan, and parts of northern India from 1530 – 1540 and again from 1555 – 1556.

The January 2003 CIA paper Iraqi Support for Terrorism states that al-Libi told a foreign intelligence service that " Iraq — acting on the request of al-Qa ' ida militant Abu Abdullah, who was Muhammad Atif's emissary — agreed to provide unspecified chemical or biological weapons training for two al-Qa ' ida associates beginning in December 2000.

Jacob suffered great loss repeatedly, as did Muhammad in the Year of Sorrow, when both Khadija and Abu Talib died.

Tabari relates ( Suyuti also relates the same through Ibn Sa'd al-Baghdadi's report ) from Aisha her description of Abu Bakr:

Upon landing in al-Andalus, Abd al-Rahman was greeted by clients Abu Uthman and Ibn Khalid and an escort of 300 cavalry.

In the early 13th century, Abu al-Abbas al-Nabati, and Ibn al-Baitar ( d. 1248 ) also wrote on botany.

Mather also took inspiration from Hayy ibn Yaqdhan, a philosophical novel by Abu Bakr Ibn Tufail ( whom he refers to as " Abubekar "), a 12th-century Islamic philosopher.

Notable works include Abu Bakr al-Razi's encyclopedia of science, the Mutazilite Al-Kindi's prolific output of 270 books, and Ibn Sina's medical encyclopedia, which was a standard reference work for centuries.

In the 12th century CE the Andalusian Muslim philosopher and novelist Abu Bakr Ibn Tufail ( known as " Abubacer " or " Ebn Tophail " in the West ) included the theory of tabula rasa as a thought experiment in his Arabic philosophical novel, Hayy ibn Yaqdhan in which he depicted the development of the mind of a feral child " from a tabula rasa to that of an adult, in complete isolation from society " on a desert island, through experience alone.

A strong emphasis on experimentation and empiricism led to new results and new observations, which were contrasted and combined with those of Galen by writers such as Rhazes, Ali ibn Abbas al-Majusi ( Haly Abbas ), Abu al-Qasim al-Zahrawi ( Abulasis ), Ibn Sina ( Avicenna ), Ibn Zuhr and Ibn al-Nafis.

There Ibn Battuta was acquainted by a local Malian merchant named Abu Bakr Ibn Yaqub, together they ventured around Timbuktu and sailed to Gao, it was during their travels that Ibn Battuta first encountered a hippopotamus, which was feared among the local boatmen because it drowned or killed local inhabitants.

After returning home from his travels in 1354, and at the instigation of the Sultan of Morocco, Abu Inan Faris, Ibn Battuta dictated an account of his journeys to Ibn Juzayy, a scholar whom he had previously met in Granada.

Abu Bakr recommended toppling a wall on the evil-doer, or else burning alive, while Ali bin Abi Talib ordered death by stoning for one " luti " and had another thrown head-first from the top of a minaret — according to Ibn Abbas, this last punishment must be followed by stoning.

Then came an even more shocking confession: according to the CIA document, al-Faruq said two senior al-Qaeda officials, Abu Zubaydah and Ibn al-Shaykh al-Libi, had ordered him to ' plan large-scale attacks against U. S. interests in Indonesia, Malaysia, ( the ) Philippines, Singapore, Thailand, Taiwan, Vietnam and Cambodia.
