Oaths & Vows

Q: I am a wife and I make serious oaths that if I do something then my nikaah is invalid with the intention of my nikaah breaking... I also make oaths that if I do not do something then my nikaah is invalid with the intention of my nikaah breaking if I break the above mentioned oaths... On numerous occasions I broke my oaths exactly like the oaths described above. Is my nikaah valid even though I broke these oaths being married and made these oaths being married?

Q: This is a three-part question related to vows/oaths. There is an individual who committed kufr (he started believing in human evolution, i.e. human beings evolved from other hominid species), but later returned to Islam.

1. The oaths that he took, and later broke, prior to committing kufr. Do these fall off (i.e. he does not have to pay kaffarah for them) because he committed kufr, and kufr wipes away all of one's past deeds (good and bad)?

2. The oaths that he took (in the state of kufr) and later broke (also in the state of kufr). Do these also fall off (i.e. he does not have to pay kaffarah for them) because he broke those oaths in a state of kufr?

3. The oaths that he took in the state of kufr, but later broke AFTER returning to Islam. Do these also fall off (i.e. he does not have to pay kaffarah for them) because he took those oaths in a state of kufr?

Q: If I stated a false oath on Quran, for example I say that I swear in the name of Quran that this thing hasn't happened etc. and that because of some complication between husband and wife, to secure their relation is that allowed in Islam? Kindly guide me because I did this to secure a relationship by saying a false oath. Was that wrong or right?

Q: If a wife takes different oaths that if she does something her nikaah is invalid and then she breaks the oath, will her nikaah break?

Q: I had a test so I prayed in my heart that Ya Allah make my exam good I won't miss any prayers from now on. I did not say it verbally. Now if I leave any prayer will I have to give kaffarah for every single one of the left prayers?

Q: One of my friends made a promise herself that 'wallahi I 'll never ask dua for my sister". Now she feels it's wrong. She likes to break her promise now. Can she break it? Is there any kaffara?

Q: A person vowed that if he never changes his school, he will stop smoking. He has not changed his school till now but he has smoked many times in this time. Does he have to offer expiation and how many?

Q: I broke an oath which meant that I had to fast for three days. Im a Hanafi and unfortunately I accidently didn't fast consecutively for three days. Does that mean I have to repeat the fasts again? 

Q:

1. A condition for a vow is that it must be verbal and therefore if one cannot remember if he made a vow verbally or in his mind is it binding?

2. If I made a vow that I will give my first months wages from my new job to charity then I spend the money, is my vow broken and will Kaffarah be necessary? Or can I give the value of the first months wages another time in the future?

Q:

1. Will my kaafaaratul yameen be done if I give ONE poor person R200, as R20 is what an average meal would cost, or will it be more. If it is more, then how much will suffice?

2. I took an oath that I will not do a certain action, and if I did then I would keep 60 consecutive fasts. I then did the action, resulting in my oath breaking. What should I do now? How many fasts must I keep and how will I cover up for breaking the oath?
