Bismillahir Rahmaanir Raheem
If one’s neighbours are poor, then to ‘braai’ outside or cook food in such a place, which would cause the aroma of that food to reach their homes, projects a lack of sympathy and mercy.
Those poor neighbours would be desirous of such food but would not be able to afford it. At such a time cook inside or at least send a little to them so that they do not feel hurt.
In a Hadeeth wherein Rasulullah (Sallallaahu ‘alayhi wasallam) enumerated the many rights of neighbours, Rasulullah (Sallallaahu ‘alayhi wasallam) also said: “…and (when a delicious food is prepared in your house), (you take care that) the aroma of your pot does not cause sorrow to him (and his children), (i.e., it does not travel to his house) except that you sent some of it to him (as a gift).”
~ Hazrat Maulana Yunus Patel Saheb (Rahmatullahi 'alayh)
