Ayatollah Al Sayyed Abd al-Husayn Sharaf al-Din al-Musawi, (Abdel Hussein Charafeddine, Sharafeddine, or Sharafeddin) (Arabic: آية اللّٰه السيد عبدالحسين شرف الدين الموسوي العاملي (المقدس)), was a Shi'a Twelver Islamic scholar[2][3] who has widely been considered a social reformer,[4] "activist",[5] and modern founder of the city of Tyre in Southern Lebanon.

[1] In 1908 (1326 AH), Sayed Sharafeddin played a decisive role in the power struggle which was triggered by the 1908 Young Turk Revolution and its call for elections to an Ottoman parliament.

"[7]In addition to his engagement in social work in Sur and Jabal 'Amil, Sayyid Sharaf al-Din continued his efforts writing and publishing.

In 1910 (1327 AH), he published Issues important for uniting the Ummah (al-Fusul al-Muhimah fi Ta'lif al-Ummah).

The book includes 112 correspondences between Sharaf al-Din and the Mufti of al-Azhar University, al-Shaykh Salim al-Bishri.

[1] After the collapse of the Ottoman Empire at the end of the First World War and the declaration of Arab Kingdom of Syria under Faisal I following the conquest of the Levant by the Sharifian Army with support from the British Empire, Sharafeddin became the leading prominent supporter of unity within a Greater Syria[8] and organiser of nonviolent resistance against the French ambitions in Jabil Amil.

[9] The pan-Arabist rule ended already after less than two years and France proclaimed the new State of Greater Lebanon under French colonial mandate.

[7] On the first of September 1920, the French colonial rulers proclaimed the new State of Greater Lebanon under the guardianship of the League of Nations represented by France.

[11] Subsequently, Sharafeddin reached "rapprochement" with the colonial regime and even entertained friendly relations with the military governor of South Lebanon, Zinovi Pechkoff,[12] whom he would regularly invite as guest of honour to religious events in Tyre.

[14] During the hajj rituals of 1340 A.H. (1922), Sharaf al-Din was invited by Malik Husayn, the king of Arabia, to lead the congregational prayers in Masjid al-Haram in which Shiite and Sunni Muslims attended.

[6] In 1365 A.H. (1946), he founded a charity institute to help people in need, and in the last years of his life, he wrote the book, al-Nass wa l-ijtihad.
