If a person is travelling for a period of less than 19 days, and he fears that due to the fact that his Islam is hidden from his hostile parents, he may be unable to pray on time, can he combine his prayers? Is it permissible to combine Dhuhr and Asr after Dhuhr time exits and Asr time enters?

Ustadh AbdulAziz al-Haqqan

If he is afraid of actual danger, then yes, he can combine prayers.
