Indian Muslim Shia group, Anjuman-e-Haideri, has offered to pay the medical bills of Ibraheem El-Zakzaky, the leader of the Islamic Movement of Nigeria (IMN) popularly known as Shi’ite.
Bahadur Naqvi, General Secretary, Anjuman-e-Haideri, told the BBC that his group had written to the Medanta Hospital, where the couple were admitted, offering to pay the bills.
El-Zakzaky and his wife, who have been in custody for four years in Nigeria, arrived India on Monday after being granted permission to travel to get medical treatment.
“We have his medical report and it will take at least six months to treat, but doctors are saying it may take one to two years because of lead poisons in his blood,” Naqvi said.
He said the group had estimated a cost of $500,000 (£414,000) based on the report given by the hospital.
However, he did not say if the hospital in Gurgaon had accepted the offer.
Aside from Anjuman-e-Haideri, London-based Islamic Human Rights Commission (IHRC) has reportedly also offered, but a source has told the BBC that it is unlikely to be given clearance by Indian authorities to do so as it is a foreign organisation.
El-Zakzaky, 66, is facing charges of culpable homicide and other offences, all of which he denies.
He has also denied that his movement, which runs hospitals and schools in some states in northern Nigeria, gets any funding from Iran.
