It is not true to say that a person has the power to adopt certain morals but not others. Not at all! There is a cure for every ailment, or in other words
لِکُلِّ دَاءٍ دَوَاءٌ
It is a pity that people do not give due regard to this blessed saying of the Holy Prophetsa and consider its scope limited to physical illnesses alone. How ignorant and erroneous is such a view! Just as there are means available for the improvement and well-being of the physical body, how is it possible that Allah Almighty would have provided no remedy for the spiritual ailments of man? Indeed, there are, without a doubt! It is a sure and certain fact that Allah the Exalted helps those who help themselves. However, the indolent and idle, are ultimately ruined.
