As-salamu alaykum, i am a revert and the only Muslim in my family. Tomorrow i have to go out with my parents for a activity. Although im not brave enough to tell them that im going to pray. The chances of me missing Dhuhr are very likely, can i combine Dhuhr and asr?

Ustadh AbdulAziz al-Haqqan

If there is danger and enough of a valid reason to do so, then you can combine. However, that is when you don't have a way out. What if you can excuse yourself and they don't see you, for example, and you're smart about it You can go and pray.
