Bu Halim's son, Najm al-Din Zarir, well known, was a commander under Ibrahim's son and successor Mas'ud III (r. 1099-1115) and is known to have made raids into India; he invaded Malwa and then further penetrated to Kalinjar and then as far to the Ganges.
His mother, a Seljuq princess named Gawhar Khatun, was treated badly, which resulted in her brother Ahmad Sanjar invading Arslan-Shah's domains, where he decisively defeated Arslan-Shah and made the latter's brother Bahram-Shah the new ruler of the Ghaznavid dynasty, while at the same time acknowledging Sejluq suzerainty.
However, Arslan-Shah managed to survive the invasion, and fled to Kurram District in present day Pakistan, where he was supported by the Bu Halim brothers and other officers.
After Ahmad Sanjar left the Ghaznavid capital of Ghazni, Arslan-Shah returned to the capital, where he defeated Bahram-Shah, but Ahmad Sanjar shortly returned and defeated Arslan-Shah, who once again fled, but was captured by a Seljuq commander, and was executed.
Imad al-Din Muhammad, who was still in India, managed to withstand an attack by Bahram-Shah, but in the end was defeated and captured at Lahore in 1119 by the latter.
