All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
Female students are permitted to go on scientific trips under certain conditions:
First: The trip should not be for long distances for which a Mahram (non-marriageable male) is required.
Second: There must be no meetings in seclusion with non-Mahram (marriageable) men.
Third: There must be no unlawful intermixing between the two sexes.
Fourth: Both should be safe from any possible temptation.
Fifth: The trip should be free from prohibited acts such as looking at forbidden things, shaking hands with the opposite sex, softening one's speech or talking idly. All these acts are not allowed with non-Mahram men.
If these conditions are met, it is permissible to take part in such trips. Otherwise, it is impermissible.
Allaah Knows best.
