Blessings come with Faith, while Kufr brings Torment

Allah mentions here the little faith of the people of the towns to whom He sent Messengers. In another instance, Allah said,

فَلَوْلاَ كَانَتْ قَرْيَةٌ ءَامَنَتْ فَنَفَعَهَآ إِيمَانُهَا إِلاَّ قَوْمَ يُونُسَ لَمَّآ ءَامَنُواْ كَشَفْنَا عَنْهُمْ عَذَابَ الخِزْىِ فِى الْحَيَوةَ الدُّنْيَا وَمَتَّعْنَاهُمْ إِلَى حِينٍ

The Arabic word بَرَکَہ :'barakah' used in this verse and translated as blessing signifies increase or growth. The expression 'blessing of the heaven and the earth' refers to all means of prosperity, like proper and timely rain from heavens (clouds), abundant and healthy produce of the earth and, above all, carefree enjoyment from their possessions with no anxiety to spoil the pleasure of things. That is, everything would have been blessed with 'barakah'.

The barakah manifests itself in two different ways. Sometimes, the thing itself increases in quantity, as is reported happening with the Holy Prophet ﷺ that a large number of people drank from a small pot of water and were satiated or the whole army was fed to their satisfaction from a small quantity of food. Sometimes, the quantity of thing does not increase but its usefulness or efficacy is increased manifold. It is usually observed that a certain thing in our household lasts as long or benefits as many people as would have done three or four things of the same kind. That is to say, certain things yield lasting benefit to people while certain other things do not, or hardly serve people either due to being damaged by accident or not being accessible in times of need.
