Ibrahim al-Mujab

Sayyid Ibrāhīm ibn Muḥammad ibn Mūsā al-Kāẓim (Arabic: إبْرَاهِيم بْنِ مُحَمَّد بْنِ مُوسَى الكَاظِمْ) also known as Ibrāhīm al-Mujāb and al-Ḍarīr al-Kūfī, was the son of Muḥammad al-ʿĀbid, and grandson of Mūsā al-Kāẓim, the seventh Twelver Shia Imam. He was the first Alid to settle in Karbala, where he died, and was buried in the Imam Husayn shrine.

al-Mujab has many descendants that are known today by various names. Al Faiz is the only line of his that remained in Karbala until this day, since he settled in 861. As for his other descendants, most of them emigrated to other cities and countries, some of them are known today as Al Qazwini, Al Hamami, Al Awadi, Al Sabziwari, and Al Khirsan. It is also reported, that the scholars al-Sharif al-Radi and al-Murtada are descendants of al-Mujab.
