Sitting for i'tikaaf in a musalla

Q: May the sunnah i'tikaaf in Ramadhan be held in a facility which accommodates and facilitates the 5 times salaah, including the jumuah salaahs. This is presently a musallah which caters for the residents in the area, over 300 Muslim homes. Consent dues have been granted already for the musallah to continue, alhamdulillah. The nearest masjid is about 4 Kms away which has a limited space for the mu'takifeen. Kindly advise if we could hold the sunnah i'tikaaf for the musallees of the area?

I'tikaaf in Musjidun Nabawi (Sallallahu Alayhi Wasallam)

Q: My question is regarding this year ramadaan. I intend on spending the sunnah ithikaaf in musjid un nabawi (17th-27th July - According to the saudi calendar). I would like to know if my ithikaaf would be valid if I leave on the eve of eid from Madinah and arrive in South Africa on the 28th, just to find that South Africa would be fasting on the 28th and celebrating eid on the 29th.What should I do in this regard? From calculations, its seems that the above scenario is most likely to occur?

Sunnah I'tikaaf

Q: I have a question about i'tikaf. If we start itikaf on the night of the 21st there is a risk that we only complete nine nights (if Ramadan turns out to be 29 days). Will the sunnah still be fulfilled in this case? Or should we start the itikaf at the night of the 20th in order to make sure that we do at least 10 nights?
