It is noteworthy that Islam requires a Muslim to be careful about his outward appearance, dress decently, maintain his dignity, and enjoy what Allah has created for the purpose of clothing and lawful adornment. The main conditions for a Muslim’s dress are to be clean, decent and cover the `Awrah. Allah counts His bestowal of clothing and adornment upon human beings as one of His favors to mankind: “O Children of Adam! We have revealed unto you raiment to conceal your shame, and splendid vesture…” (Al-A`raf: 26). Even people are required to pay attention to their appearance particularly when going to places of worship. Almighty Allah says: “O Children of Adam! Look to your adornment at every place of worship…” (Al-A`raf: 31)
Dr. Muzammil H. Siddiqi, former President of the Islamic Society of North America, states: “A Muslim’s dress should be clean, honorable and decent all the time. At the time of prayer and especially when one comes the Masjid one should pay special attention to one’s dress. There are many Ahadith of the Prophet, peace and blessings be upon him, that speak against making pictures. Although according to many jurists the photographic pictures do not come in the category of the pictures that are forbidden in Islam, nevertheless all jurists are unanimous that the places of worship must be free from any human and animal pictures.
No pictures of any kind should be present at the places of worship. Muslims also should not wear pictures or hold pictures when praying. This is to preserve the Tawhid or the Oneness of Allah and to avoid any form of Shirk in the places of ‘Ibadah”
