allah does not take you to task for oaths which are made unintentionally but he does take you to task for oaths which you ratify so the redemption of such oaths is to provide food to ten needy persons equal to the average of what you feed your family or to clothe them or to free one slave and for one who has no means is the fasting for three days this is the redemption of your oaths when you have sworn and fulfil your oaths this is how allah explains his verses to you so that you may be thankful.
لا يؤاخذكم الله باللغو في أيمانكم ولكن يؤاخذكم بما عقدتم الأيمان فكفارته إطعام عشرة مساكين من أوسط ما تطعمون أهليكم أو كسوتهم أو تحرير رقبة فمن لم يجد فصيام ثلاثة أيام ذلك كفارة أيمانكم إذا حلفتم واحفظوا أيمانكم كذلك يبين الله لكم آياته لعلكم تشكرون
