(RIGHTS)
Rights of Animals
1. Do not encage an animal which you will not be taking any benefit from. Removing nestlings from their nests, causing harm to their parents, etc. is a sign of extreme mercilessness.
2. An animal that is suitable for consumption should not be killed merely for amusement.
3. You should make proper arrangements with regard to food, drink, providing rest, and taking care for the animal that you utilise for your work. Do not impose any work on it that is beyond its capacity, nor should you beat it more than necessary.
4. The animal that is to be slaughtered or killed on account of it being harmful should be slaughtered or killed quickly. Do not cause it any agitation. Do not take its life after having starved it.
Additional points
If there is any shortcoming in fulfilling the rights of a person, fulfil that which can be fulfilled or else, ask for forgiveness. For example, you are still owing someone some money or you cheated someone, etc. (In such a case you should try and pay the debt, but if you cannot do so, then seek forgiveness from the person). As for the right which can only be forgiven, seek forgiveness for it, e.g. you spoke ill of a person or beat him (In such a case, it is obvious that you cannot pay him anything. Instead, you will have to seek his forgiveness).
If, due to some reason, you cannot fulfil their rights nor can you seek their forgiveness, then you should continue making du‘â for these people. It is possible that on the day of judgement Allah Ta'âlâ will try and influence them to forgive you. However, later if you are in a position to fulfil their rights or seek their forgiveness, then do not hesitate in doing so.
As for the rights that are due to you and there is a hope of their being fulfilled, then be lenient when asking for them. As for those where there is no hope of their being fulfilled or, they are such that they cannot be fulfilled, such as ghîbah , then although there is the hope of your receiving rewards in return for them on the day of judgement, however, more reward has been mentioned with regard to forgiving them in this world. It will be much better if you forgive them completely or absolve them completely. This is especially when the person earnestly seeks forgiveness from you.
