I'tikaaf

Q: I would like to have some clarity regarding the issue of having a shower while in sunnat itikaaf. According to some Ulama, the only time one could have a ghusl, not a shower, is if one had a wet dream in the musjid and is forced to make ghusal.

The permissibility of allowing people to have have showers with no valid reason has started very recently over the last few years and was never heard of in the past unless compulsion of ghusal.

Q: A brother made intention to spend the last 10 days of Ramadhaan for i'tikāf. On the second day, due to a person passing away in his family (non-Muslim) his dad wanted him to leave his i'tikāf because he (his dad) had to go to the deceased's home and it would take a few days for him to return. So his dad wanted him to break his i'tikaf to look after his home and animals (pets). The brother had no choice but to break his i'tikaf on the second day.

1. How does he have to do qadhaa of his i'tikaf?

2. He intends to do qadhaa of his i'tikaf this Ramadhaan Insha Allah so will the fast in Ramadhaan suffice for him to keep his i'tikaf or does he have to keep fast outside of Ramadhaan to make up his qadhaa.

3. How many days does he have to do qadhaa for, 1 or 10 days. 

Q:

1. If a person in i'tikaaf leaves the masjid to go to the toilet, and at the same time has a shower, will his i'tikaaf break?

2. What if he has a long shower, will this matter?

3. If he goes to the shop to buy something after going to the toilet, would this break his i'tikaaf?

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?
