The greatest jihad
Question:
Is Jihad in the way of Allah the same regardless of whether it is with one's life, wealth , or supplication , even if somebody is cabable of the type that involves one's life?Answer:
There are different kinds of jihad - with one's self, wealth, supplication, teaching, giving guidance, or helping others in good in any form.The highest form of jihad, however, is with one's life (the intent here is not suicide, for that is forbidden in Islam), then comes Jihad with one's wealth and jihad with teaching and guidance, and in this way Da'wah is a form of jihad, but jihad with one's life is the highest form.
