A mosque (; from Arabic: مَـسْـجِـد, romanized: masjid, lit. place of ritual prostration) is a place of worship for Muslims.Any act of worship that follows the Islamic rules of prayer can be said to create a mosque, whether or not it takes place in a special building. Informal and open-air places of worship are called musalla, while mosques used for communal prayer on Fridays are known as jāmiʿ.
It is highly recommended to give Sadaqa every day and it is better to give Sadaqa every morning and every evening. You can collect the amount and give it to the needy or to trusted persons who make it reach to the needy as soon as possible.
Real Islamic rules do not need such validation document because your faith in Islam (THERE IS NO GOD BUT ALLAH, MUHAMMAD IS THE MESSENGER OF ALLAH) in enough to be a Muslim.
Some Muslim governments ask for a document of being a Muslim from those who were born as non Muslims. Such document can be issued by a mosque or Islamic organization for getting a visa for Hajj or Umrah. It is never compulsory to get such document to be a Muslim. Visa requirement to Macca is different from the conditions to be a Muslim.
Jum'a Prayer has many conditions including that it should not be performed if another valid Jum'a Prayer is been performed in radius of 3 miles. If the Jum'a Prayer near your area is not valid according to Ahlul Bayt (AS), then you are allowed to perform a valid Jum'a Prayer with minimum of five participants including the leading person who must be having all the conditions including being 'Aadil ( pious) with perfect recitation of the Prayers.
Masjid remains Masjid till the Day of Judgement and no way to change it to any other use. We can not change a Masjid to imambargah or to an orphanage or to a school even a religious school. All activities of Imambargah, religious school and helping orphans etc can be done in the Masjid but it remains a Masjid only.
'In some places, Masjid and Imambargah are built together on the same building by making the Qibla side of the building as a Masjid, and the other side as an Imambargah.
Do you think you might have an allergy to some things on other people (such as cologne, pet dust, laundry detergents, foods, etc) which become magnified when you are in a crowd close together, or some things at the mosque (carpet, dust, mold/mildew, etc)?
And could there be a psychological reason too, such as social anxiety?
Anyway I hope you are able to find a cure for your itching, inshallah.
Majority of our Shia Masjids all over the world do not place pictures of scholars or founders of the mosque, but in some places there are pictures of respected scholars where the culture of that area allows placing pictures. Those who place picture for respected Scholars do so to express gratitude to the great services rendered by them to the community. We don't have any authentic evidence against placing pictures in Masjid as far as it is not for worshiping it and it is just a picture and not a statue. The pictures should not be in the direction of Qibla, means should not be faced by people while performing Namaz because it Is Makrouh (disliked) to face a picture while performing Namaz.
Yes it is permissible to pray Eid prayers in Sunni mosque. Eid prayer can be performed in congregation ( Jama'ah) as well as individually (Furada). When pray with congregation of Sunni brothers, you need to recite every Sura and Du'a in whispering without clear voice. This is exactly like praying any prayer with Sunni congregation.
Thank you for your question. Shias do not have any restrictions for other denominations of Muslims to enter a mosque. Rather, a mosque should be a safe space for all Muslims. Perhaps there may be local cultural sensitivities which you will have to assess on a case by case basis.
May you always be successful
If you are in hurry and can't wait till Jama'at starts, you can pray individually (Furada) but it should not send a wrong message of disrespect to the Imam of Jama'at or to the participants who are waiting to join the congregational Prayer.
Friday (Jum'ah) Prayer is obligatory if it was called for with all its conditions. This is according to the obligatory precaution ( Ehtiyat Wajib) according many of our leading scholars.
Jummah prayer can never be performed individually (Furada). It must have all its conditions including number of participants of minimum five in congregation.
Yes. We are encouraged by Ahlul Bayt (AS) to pray in any Masjid and with Muslims of any sect.
Shia great scholars (Maraaji' of Taqleed) allow reciting Quran in any of the famous seven recitations including the Qira'ah of Warsh, although we believe that the Qira'ah of Hafs from 'Aasim is the most authentic as it was taken from Ameerul Mo'mineen Ali (AS).
We are allowed to pray behind any Muslim following any Muslim sect apart from Shia Islam, but we need to recite Al-Hamd and Sura whispering,bin the first and second Rak'ats for ourselves.
