Former world heavyweight boxing champion Muhammad Ali passed away on 3 June at the age of 74, due to a respiratory condition complicated by Parkinson's disease. Known as the 'Greatest', Cassius Clay who changed his name to Muhammad Ali after converting to Islam, was not only the best in the boxing ring but also outside in the real world.

The former champion is ranked as one of the greatest boxers of all time, with many magazines and publications putting him at number one on their list. Ali defeated every top heavyweight of his era and was voted by BBC as the 'Sports Personality of the Century'. The 'Greatest' eventually retired with a 56-5 win-loss record.

Part of Muhammad Ali's legacy and charm was his quips outside the ring. Known as a brash talker Ali always spoke about the realities of life during his time and was known not to hold back.

IBTimes UK takes a look at some of his most famous quotes.
