Ramadhaan & Fasting

Qadhi announcing Eid

Q: If a person is going on jamaat to an Arab country for ramadan and eid, and in that country they use scientific methods to determine the date of eid without actually seeing the moon, should one celebrate eid with them? If not, should one look for the moon and if not seen, fast on their eid and celebrate eid the next day?

Fasting without sehri

Q: My question is a night before Rajab (miraaj un nabi) I made intention of fasting keeping roza. I stayed up a little with some ibaadat so I thought I will take a hours rest an then get up for sehri but I didn't realise I fell asleep and woke up next morning. Can you please tell me if I am gunaghaar an will my fast be accepted? Can I carry on fasting during the day or not?

Changing one's niyyat before the fast commences

Q: I made a niyyat for a nafil fast about 30min before sehri ends. Just prior to sehri ending, I decided that I should rather wait and make the niyyat for keeping fast before half the day, depending on how I felt. I was not going to eat during that time, until my niyyat was confirmed. Is it ok to change my niyyat for fasting afterwards, or is the first niyyat I made 30 minutes before sehri ended binding?
