Assalam walaikum, I would like to know in islam can a person take advantage of someone. Is there any quotes from the Quran or hadith about this. I have a friend (person A) who got help from a family member (person B) to get his daughter married. Now when ever person B calls person A to have him do something. Person A feels like he is obligated to go and help person B even if he has to miss work. He is a uber driver but he does miss the days that is busy. Person A feels like he is a puppet what ever person B ask he has to do it. If I can get a quote from the Quran and hadith about this so I can show person A so he won’t feel guilty for not helping person B.
