In him are found both love and hatred, generosity and coveteousness, compassion and aggression. Moreover, there have existed until now not just one but several 'humanities' with their own religious and moral norms and national, ethnic and racial groups with their own bonds of affiliation.
As a result the practice of jihad as applied to the world of multiplicity and the vicissitudes of human existence in the external world has come to develop numerous ramifications in the fields of political and economic activity and in social life and come to partake on the external level of the complexity which characterizes the human world. In its most outward sense jihad came to mean the defence of dar al-islam, that is, the Islamic world, from invasion and intrusion by non-Islamic forces.
The earliest wars of Islamic history which threatened the very existence of the young community came to be known as jihad par excellence in this outward sense of 'holy war'.
But it was upon returning from one of these early wars, which was of paramount importance in the survival of the newly established religious community and therefore of cosmic significance, that the Prophet nevertheless said to his companions that they had returned from the lesser holy war to the greater holy war, the greater jihad being the inner battle against all the forces which would prevent man from living according to the theomorphic norm which is his primordial and God given nature.
Throughout Islamic history, the lesser holy war has echoed in the Islamic world when parts or the whole of that world have been threatened by forces from without or within. This call has been especially persistent since the nineteenth century with the advent of colonialism and the threat to the very existence of the Islamic world.
It must be remembered, however, that even in such cases when the idea of jihad has been evoked in certain parts of the Islamic world, it has not usually been a question of religion simply sanctioning war but of the attempt of a society in which religion remains of central concern to protect itself from being conquered either by military and economic forces or by ideas of an alien nature.
This does not mean, however, that in some cases especially in recent times, religious sentiments have not been used or misused to intensify or legitimize a conflict.
