"We remember Usama’s jihad against the Soviet Russians at the beginning of this Islamic century, when he dedicated himself with a group of mujahideen to collect funds and mobilise efforts to support the oppressed poor of Afghanistan. When the Russians were expelled in 1409 AH (1998), and the Afghans regained control of their country, many of the Arab mujahideen returned to their countries except that Usama and a group with him refused."
