Musnad Ahmad 1156:5

Sufyan ibn 'Uyaynah narrated to us, from Ibn Suqah, from Nafi' ibn Jubayr, from Umm Salamah: The Prophet, peace and blessings of Allah be upon him, mentioned the army that will be swallowed up [by the earth]. Umm Salamah said: "Perhaps there are those among them who are coerced." He said: "They will be resurrected according to their intentions."
