The wet-nurse

Meet her with respect. If she is in need of money and you are able to help her, then help her.

The Step-mother

Since she is an associate of your father, and we have been commanded to be kind and friendly to our parents' associates, the step-mother, therefore, also has certain rights over you as mentioned previously.

The elder brother

In the light of the Hadith, the elder brother is similar to one's father. From this we can deduce that the younger brother is similar to one's children. Based on this, they will have rights similar to those of parents and children. The elder sister and the younger sister should also be treated in the same manner.

Relatives

If any of your blood relatives is in need and is unable to earn, help him out with his expenses according to your financial position. Go and meet them occasionally. Do not cut-off relations with them. In fact, even if they cause you harm, it will be best for you to exercise patience.

The In-laws

In the Quran, Allah Ta'ala has mentioned the in-laws together with one's lineage. We learn from this that the father-in-law, mother-in-law, wife's brother, sister's husband, son-in-law, daughter-in-law, the previous children of the wife, the previous children of the husband - all of these have certain rights. Therefore, you have to be more considerate to them as opposed to others.
