As you may deduced from the title I'm a sunni living in Belgium, Europe. Sunnism is commonly regarded as a less orthodox muslim community than shiism (correct me if I'm wrong). One of the implications are that one postpones salats if there comes something in between him and him performing the salat like university or work. That's why I often pray Duhr, Asr and Maghreb together if I come home at 7.00 pm from university since I need to be there at 8.30 am. The reason why I stay so late at the university is because I can concentrate much better there than at home.
I wonder why if my way of postponing salats is permissible or not?
Please elaborate your answer till you think you have provided everything you know on this matter and please link some references to it so that I can look all the elaborations of the authors myself.
LS: My apologies for the misspellling of the words since for some there isn't a consensus on how to write it properly because most write it phonetically.
