Combining prayer

dear sheikh..as-Salamu `alaykum wa Rahmatullahi wa Barkatuh. because of school i am unable to pray duhr salat since it starts right when our lunch finishes i wanted to know if it's stil considered a sin for me not praying it?

this is regarding jammu & qasr (combining % shortening of prayers while traveling) if i want to do duhr prayer with asr at the time of duhr, is it wrong to delay asr after duhr prayer.i hear thatimmediately after duhr we must pray asr when we r combining the prayers.now if i am doing duhr with asr at the time of asr, and i find out that the jamaath of asr is taking place in a mosquewhat am i suppose to do.ie do asr with jamaath and then prayer duhr..plz clarify.

Dear scholars, As-Salamu `alaykum. Very often I cannot pray `Asr and after a long travel, by the time I reach home it is Maghrib time. Can I combine my `Asr and Maghrib Prayers? Jazakum Allah khayran.

Dear scholars, as-salamu `alaykum. Is it allowed to combine Prayers during rain?
