From the route of Ibn ^Abbas, may Allah accept both of their deeds, who said: the Messenger of Allah, sallallahu ^alayhi wa sallam, said:
<< Allah does not hold my nation accountable for the errs that they do unintentionally, forgetfully or coerced (threatened by death and the like) into doing.>>
This Hadith is hasan and was narrated by Ibn Majah, al-Bayhaqiyy and others.
