Allāh Ta‘ālā mentions the blessings the people of Jannah (Paradise) will have in the 28th and 29th āyahs of Sūrah al-Wāqi‘ah: “They (Ashāb-e yamīn whose books will be given from the right) will be among thornless cherry-trees, and banana trees layered [with fruit].”
Mujahid (rahmatullāhi ‘alayhi), a great mufassir from the tābi‘īn stated: “The people of Ta’if had a valley with orchards of banana, plantains, and cherries that used to astonish anyone who saw them. The Muslims who saw that valley would yearn for it, saying: “If only valleys like this would be given to us in Jannah.” Upon that, Allāh Azza wa Jalla revealed these (above mentioned) verses.”
Bananas are delicious tropical fruits that are rich in starch. The fruits grow in big clusters and 50-100 bananas can grow in one cluster. They are harvested before they ripen so that they can be kept without getting spoiled for a while.
Bananas have many curative features. They promote brain functions, support nerves, clear the mind, and facilitate digestion. Their calcium and vitamin D contents strengthen bones and teeth. They help children grow.
Bananas are rich in potassium and are very good for kidneys. They balance blood pressure and support heart muscles. They are rich in fibre, minerals and vitamins such as potassium, calcium and magnesium. However, those having kidney, heart and diabetes problems and those on a diet are recommended to be careful about their consumption as they are rich in nutrients. One regular-sized banana provides 100 calories. Its excessive consumption is harmful as is the case for everything.
Unripe bananas contain resistant starch that is hard to digest, which might also cause constipation. They are good for diarrhoea. Although they alone may not heal diarrhoea, they help tremendously to regain the lost minerals.
Like many other fruits, bananas are advised to be consumed on an empty stomach or before meals.
