Mufti Muhammed Taqi Usmani Sahab (DB) has narrated in one of his travelogues that people of Algeria were still pondering over some things which were already solved in Mufti Sahab (DB)'s country. The specific problem was of alcohol. Whether banning of alcohol can be implemented. Some people may quip that there is lots of alcohol in Pakistan so what is the meaning of this statement. Things have to be compared with western situation in regards to alcohol to understand the meaning of above statement. Conclusion : If you think that an Islamic injunction is too impractical to implement then look for an example where it has already been implemented.
