Khomeini and Mostafa entered Iraq. He went to Kadhimiya and stayed in the company of Mohammad al-Husayni al-Shirazi for two days before going to Karbala. From there he went to the city of Najaf.[27] Initially, Khomeini was isolated by Iraq’s Shi'a clergy because of his status as a foreigner and his radical teachings and support for terrorism;[20] however, after a while Muhammad Baqir al-Sadr and other Iraqi clerics would join with Khomeini because they shared similar aims in establishing an Islamic state.[20] Khomeini would also be helped in his first days in Iraq by then-President Abdul Salam Arif, who allowed the Ayatollah to set up and control an Iranian opposition radio station.[20]
