Permanent marriage is not available for lots of people, especially young persons, because generally permanent marriage needs preliminaries, costs and responsibilities which many people are not prepare to accept them. For instance:

1- Lots of youths in their study period, especially in this age which period of study lengthened, cannot perform permanent marriage, because they have no job, no proper home and other costs and even they want to marry very simple, still condition are not available.

2- There are people who are married, but they have to be in long travels far from their homes, and sometimes when these travels got to long they come under the pressure of lack of sexual interests, neither they can brought their wives with themselves nor they have possibilities of permanent marriage in there.

3- There are people whose their wives have illness and cannot fulfill their sexual needs.

4- There are soldiers who are in long missions for defending their country far from their families and they are involved in sexual problems, and as we will see in the age of holy Prophet (s.a.) the same problem occurred for soldiers of Islam and this matter caused canonization of temporary marriage.

5- Sometimes during pregnancy and its special conditions, husband cannot have sexual relation with his wife and maybe he might be young and involved in sexual deprivation.

These social necessities and problems have always been and are not only for the age of holy Prophet (s.a.), but nowadays with these much of excitants and stimulants it has got more severe by the time.

Proposing to piety and abnegation of both is a good proposal, but it is not practical for some people and at least it seems like fantasy for a group.
