Reference excerpt

Ilyas ibn Mudar (Arabic: إلياس بن مضر) also spelled al-Yas was a pre-Islamic Arabian tribal chief and an ancestor of the Islamic prophet Muhammad. He is the progenitor of the Khindifite tribes, such as the Quraysh. A pioneer of pre-Islamic monotheism, Ilyas ibn Mudar lead a period of religious reform during his rule over the Hijaz to eradicate the worship of idols.

Biographical information

Birth His full birth name which shows his lineage is Ilyas ibn Mudar ibn Nizar ibn Ma'add ibn Adnan; which indicates he is a fifth-generation descendant of the Arabian patriarch Adnan through Mudar. The name of Ilyas has also been rendered as al-Yas. He was a descendant of biblical patriarch Abraham through Ishmael.

Family Ilyas was born to Mudar ibn Nizar and had a brother named Qays Aylan, the progenitor of the Qays tribal confederation. His mother was an Arab woman named Rabab. The wife of Ilyas was named Khindif. Ilyas' sons were Amir, Amr and Umayr, whose names were later changed to Mudrikah, Tabikha and Qam'ah respectively. Through Mudrikah, Ilyas is the ancestor of the Banu Hudhayl.

Life

Rule over the Hijaz Ilyas ibn Mudar succeeded his father as the ruler of the Hijaz. During his rule, he maintained the Kaaba in Mecca and was the first to start the custom of slaughtering an animal on the premises of the Kaaba. Ilyas also rediscovered the Maqam Ibrahim, repaired it, and then placed it in a corner of the Kaaba. In his old age, Ilyas died of tuberculosis and was the first Arab recorded to have died from it.

Religious reforms Ilyas ibn Mudar followed a monotheistic form of religion that was incompatible with the pre-Islamic Arabian polytheism. As such, he openly denounced idol worship to the mixed reactions of his people, who would eventually accept his opinion and follow him in rejecting polytheism. Ilyas' reforms resulted in a period of the rise of monotheism in pre-Islamic Arabia until the arrival of 'Amr ibn Luhay. Ilyas' grandson, Khuzayma ibn Mudrika would be the first to set up the idol of Hubal which the Arabs worshipped for generations until the rise of Islam in the 7th century CE.

Ilyas in the Islamic tradition The 11th-century lexicographer, Abu Hilal al-Askari stated in al-Awāʿil that Ilyas was mentioned in the Qur'an, specifically in a verse in the chapter as-Saffat which says "Peace be upon Ilyas." Meanwhile, a Hadith forbidding cursing Ilyas due to his monotheism has been narrated as well. Twelver Shi'ites believe that the ancestors of Muhammad were spared from accepting polytheism, which includes Ilyas and his father Mudar.

Worked examples

Example 1 — a first encounter with Ilyas ibn Mudar

Start with the simplest possible case. Write down what Ilyas ibn Mudar claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ilyas ibn Mudar before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ilyas ibn Mudar ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ilyas ibn Mudar

In research: Ilyas ibn Mudar appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ilyas ibn Mudar in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ilyas ibn Mudar is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ancestors of Muhammad, Muslim reformers, so understanding it makes those chapters shorter.
In everyday life: Look for Ilyas ibn Mudar outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
