I have arrived to UK in search of job and due to lack of accommodation my family is staying with Hindu family. They are very humble and down to earth and always force us to eat food they prepare.. many a times we make excuse but sometime they force us to eat. We might stay in the temp accommodation for more 5 days. Please guide me as to how I need to avoid and seek forgiveness to Allah SWT

Just be open with them. Buy them a nice gift to show your kindness and then tell them you can only eat food prepared by Muslims. Tell them your food requires special prayers to be recited on and so you can only eat food prepared by Muslims. Just be open with them even if they might be offended a little
