Hazrat Umar (Umar ibn Al-Khattab) was born in 584 AD, which is before the Hijri calendar started (622 AD). Therefore, it is incorrect to say he was born on a specific Hijri date. Options B and C are incorrect as they reference Hijri dates after his birth. Option A gives his birth year in AD, which is correct, but the question asks 'on which hijri?', implying a Hijri date, so the best answer is D (None of these).

Ada Bin Hatam Tai embraced Islam in the 6th year of Hijri. This is a well-documented fact in Islamic history, marking his acceptance of Islam during the early years of the Muslim community.

Hazrat Umar bin Abdul Aziz is widely recognized as the first Mujaddid (reviver) of Islam. Imam Ghazali is commonly regarded as the second Mujaddid due to his significant contributions to Islamic theology and philosophy, revitalizing Islamic thought in his era.

Bait-ul-Hikma, or the House of Wisdom, was founded during the Abbasid Dynasty, specifically under Caliph Harun al-Rashid and flourished under his son Al-Ma'mun. It was a major intellectual center in Baghdad for translation and scholarship.

Zulqarnain is mentioned in Surah Al-Kahf (Surah 18) of the Quran, specifically in verses 83-101. None of the other options correctly identify the Surah containing this mention.

Masjid al-Khaif is located in Muzdalifah, which is a significant site visited during the Hajj pilgrimage. It is not located in Arafat or Mina, making option A the correct choice.

Imam Shafi'i is historically recorded to have taken the office of religious judgement (fatwa) at the age of 13, which is a notable fact about his early scholarly achievements.

The nickname 'Sahib Us-ser' (meaning 'Master of the Sword') is attributed to Hazrat Khalid Bin Waleed (RA) due to his exceptional skills in battle and swordsmanship.

Mashar-al-Haraam is another name for Mina Valley, a sacred site during Hajj where pilgrims stay in tents. The other options, Muzdalfa and Arafat, have different names and significance.

The Kitab al-Umm is a foundational work of Islamic jurisprudence authored by Imam Muhammad ibn Idris al-Shafi'i, the founder of the Shafi'i school of Sunni Islamic law. It is an exhaustive compendium of Islamic law and is considered the authoritative guide for the Shafi'i madhhab. Therefore, the correct answer is Imam Shafi (option C).
