Mullah will make anything haraam or halal if it suits his own interest.
Mullahs going against the ruling of the Quran is very common and unfortunately, Muslims follow these mullahs without using their God-given intellect and reasoning.
"And of mankind is he who purchases idle talks (i.e. music, singing, etc.) to mislead (men) from the Path of Allah without knowledge, and takes it (the Path of Allah, the Verses of the Quran) by way of mockery. For such there will be a humiliating torment (in the Hell-fire). "[Luqmaan 31:6]
