I am sensitive to it. I live in hostel so can’t cook food myself. I recite 3x bismillahilazi la yaduru…..aleem and blow on food. Is it ok to take food recite khatamul-khwajagan for it?
If you are in a Muslim hostel then you should trust in Allah and eat, as any suspicion about food in such a setting is waswasa. If you know or are mostly sure that the food is haram then it is forbidden to eat.
The sunna before food is to recite Allahumma barik lana fi-ma razaqtana wa-qina `adhab al-nar without blowing.
Adab of personal recitation of Khatm al-Khwajagan requires a quiet secluded place any time of day or night.
