Q21: If a student of religious knowledge is not able to travel in order to continue his studies or teach for reasons that are beyond his control, but he can learn or teach through the internet, is he entitled to receive Khums funds just as other students who actually attend the religious seminaries?
This is not a general religious ruling that we can present. Rather, it depends on each individual case that is addressed by the jurist or whoever represents him in managing these funds.
Q22: If the student of religious knowledge spends part of his time in teaching or learning to make programs to be used on the computer and he creates them to make religious research accessible to the students of the religious knowledge, makes the subjects easily accessible and helps students in writing on subjects in response to the fallacies. Does this affect his entitlement to receive the stipends given to the religious students in return for his efforts in this way?
The answer to this question is the same as the last one.
Q23: If an individual launched a website on the internet that specializes in the affairs of the students of religious knowledge, to propagate their activities, to present their articles and research, to allow them to have dialogue with each other and similar services, does he need a special permission from the Hakim Shar’i?
There is no need for permission from the Hakim Shar’i in this case, since it is a recommended action by itself, unless this would lead to certain other obstacles, like when some participants in dialogue use this opportunity to insult whoever does not deserve to be insulted, exaggerate problems in such a way that leads to the discouraging of others from serving the religion etc. It is required to take extra care when allowing communications amongst them and have good control, in order to avoid such obstacles and problems.
