break

I made a promise in Allah's name that i will not do a particular thing. now i want to do that thing. what am i supposed to do. if i break this promise , what should i do for repentance

Assalamu aleikum,hope you all are in the best health and iman. my question is regarding the first night of the wedding.please can you give me details on how the husband should break the hymen of his wife and when it bleeds how should the wife take care of it so that it doesn't form a wound.another question is: is it allowed for the husband to ejaculate inside after breaking the hymen? or first the wife has to wash the blood which came out?please i need the answers because am soon going to get married and i dont know about that.Jazakallahu kheiran Ma'asalaam.

Respected scholars, as-salamu `alaykum. It's said that we should listen to the Adhan. But what about a person who is breaking his fast on hearing Maghrib Adhan? Is he exempted? Jazakum Allahu khayran.
