A few years ago I went for ‘umrah with my brother and his wife during Ramadan, and I did not know whether they would be fasting whilst travelling or not, and I felt too shy to ask them. I thought: if they fast, I will fast with them, and if they break the fast I will break the fast with them. When dawn broke, I was still hesitating whether to refrain from eating or not, then my brother told me that they were fasting, at which point I intended to refrain from eating, but that was after the sun rose. A few days ago I read that in order to fast, one should form a firm intention before dawn. So I decided to fast that day and I did fast it. My question is: do I have to offer expiation as well or not, because that was five years ago? My second question is: I seem to remember that my sister was also hesitant. Should I tell her that she has to make up the fast or not, because I am not sure that she was hesitant like me, and I am afraid that she will tell me that this is waswaas (whispers from the shaytaan).
