According to a Hadith after we come back from a long journey e.g. Hajj or Umrah we can give dawat to our friends, we should also keep in mind that this should be done for only Allah’s sake and not for rayakari, dikhawa.Nabi (S.A.W.W) used to not take anything from a stranger until he could trust the stranger or the stranger would also eat with him. Mominal ways shares his food with others,this adds barkat in the food. According to a Hadith if a fly falls into your food, you should immerse it whole in the food and then take it out for its one wing has bemari(disease) while the other has shifa. Nabi (S.A.W.W) has told us that if we go to someone’s place as a guest, we should happily eat whatever the person has provided us with and should refrain from pointing out the errors.
