{ Allah does not hold you all to account for the slips in your oaths; Allah does however hold you to account for what your hearts have attained; and Allah is forgiving, forbearing } Al-baqara 225

{ Allah does not hold you all to account for the slips in your oaths } : this is someone who swears to something, thinking that there is truth in it, while it is actually wrong; Allah does not hold him to account for it, and there is no atonement required of him for it – this is the forgiveness.
