What is the ruling on praying in a car or at an airport, or combining prayers, or eating food in non-Muslim countries with the possibility of it containing forbidden ingredients?

Delaying the 'Asr prayer until Maghrib without a valid excuse is a grave sin that necessitates repentance. It is permissible to combine the Dhuhr and 'Asr prayers, and the Maghrib and 'Isha prayers, during travel and in other circumstances detailed in fatwas. Praying in a car due to fear of missing the prayer time is valid if one fears being separated from their companions, but it is more cautious to repeat it. Foods are originally permissible unless there is a strong presumption of their unlawfulness. As for slaughtered animals, it is not permissible to consume them unless one is certain that they meet the conditions for being lawful.
