In Albania Halal slaughter of animals and food is permitted, mainly available in the eateries of large urban centres and becoming popular among people who are practicing Sunni Muslims.[150] No centralised organisation exists for Halal certification of food which is unavailable in Albanian state institutions like schools, army, hospitals and so on and people requesting Halal food in those places are usually sidelined. Muslim dress is not prohibited in Albania in public areas.[150] Unofficial restrictions and regulations on religious clothing worn within public institutions in order to maintain the secular status of the state were upheld by principals of schools and others.[150] Examples included within schools and universities whereby some young women wearing the hijab were expelled or told to remove it.[150] These have eased especially after the Albanian government in 2011 backed away from proposed legislation that would have officially banned displays of religious symbols in schools.[150] Religious Muslim law as with other religious law is not recognised by the Albanian courts.[150] The Sunni Muslim Community of Albania however recognises nikah or religious Muslim marriage although not many people undertake marriage in this form.[150] While chaplaincy though not officially recognised within state institutions, access to, religious advice and preaching in prisons is allowed to inmates while chaplains are banned in state schools.[150] During the communist period Muslim Albanians were buried alongside Albanians of other faiths and due to that legacy in contemporary times separate Muslim graveyards are uncommon.[155]
