How can one easily learn the English language in a way that is compliant with Islamic Sharia, and what are the supplications that help in achieving success in studies?

Among the fundamental matters for human success are faith in Allah and reliance upon Him, and one should turn to Him asking for success (tawfiq).

To learn a language, ask those with experience, exert effort, persevere in your studies, and do not despair.

Learning languages is permissible in Islamic law, but avoid potential prohibitions.

Allah Almighty hears supplications in every tongue, and the best supplications are those authentically reported from the Prophet, peace and blessings be upon him.
