What is the difference between 'Wahi' and 'Ilham'?

In Islamic tradition, 'Wahi' and 'Ilham' both refer to forms of divine communication or inspiration, but they have distinct meanings and implications.

'Wahi' is typically understood as revelation, which is a more formal and direct communication from Allah to His prophets. This includes the Qur'an itself, as well as other divine messages given to the Prophets, such as the teachings and laws that guide the Muslim community. The Qur'an states, And verily We gave Luqman wisdom, saying: Give thanks unto Allah; and whosoever giveth thanks, he giveth thanks for (the good of) his soul. And whosoever refuseth - Lo! Allah is Absolute, Owner of Praise. 31:12. This verse indicates that wisdom and guidance can come directly through divine revelation, which is a hallmark of 'Wahi'.

On the other hand, 'Ilham' refers to a more subtle form of inspiration or intuition that is granted to individuals. It is not necessarily a formal revelation but can be an insight or understanding that guides a person's thoughts or actions. 'Ilham' can occur to anyone, not just prophets, and is often seen as a means through which Allah inspires individuals to do good or make correct decisions.

The primary difference lies in the nature and recipient of the communication: 'Wahi' is a direct and formal revelation intended for prophets, while 'Ilham' is a general inspiration available to all believers, guiding them in their lives without the formalities of divine messages.
