Does one get sick due to fasting?

سُـبْحٰـنَ الـلّٰــه عَزَّوَجَلَّ! Have you noticed the excellent method that Islam has bestowed upon us to attain the blessing of health and to attain lots of Sawab, that the person who for the pleasure of Allah عَزَّوَجَلَّ observes only one fast, Allah عَزَّوَجَلَّ blesses him with health along with an excellent reward! Just ponder when this is the reward for just one fast, then who can guess the reward and the gifts which are given to the fortunate ones, who observe fast for the whole month of blessed Ramadan, by Allah عَزَّوَجَلَّ?

Alas! Some people have been heard saying that we fast in such-and-such a month or fast the whole month of Ramadan regularly, but instead of being healthy we fall ill and cannot do anything while fasting; we feel as if our body has become lifeless etc. Remember! This has absolutely nothing to do with fasts, but rather problems lie in us. For example, some people eat and drink more than they should, in this way if they put more burden on their stomachs and eat fatty, oily and spicy foods, butter loaves, burgers, barbecue items, Samosas, rolls, pakoras, cold drinks, biryani and many other such foods too much in Sahari and Iftari, then how many things can the stomach digest? As a result, the digestive system will get disturbed; the stomach will become upset and will cause illnesses to the body.

As our Beloved Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم has rightly stated, ‘The stomach is like a pond in the body and the veins are the streams which proceed towards this pond. If the stomach is healthy, the veins return with health and if the stomach is ill, the veins return with disease.’

(Shu’ab-ul-Iman, vol. 5, pp. 66, Hadees 5796)

Therefore, one should be very careful when whether fasting or not. Furthermore, one should avoid working more than his normal strength in fasts, because if he works more than his strength in the state of fasting, it will leave bad effects upon his body and it will become difficult for him to observe fast or to accomplish the work whilst fasting. Unfortunately, in Ramadan, due to the greed of earning money some unwise Muslims instead of worshipping abundantly in fasts, they do more tough work than their strength can handle and this causes weakness to their body. As a result, they are no longer able to
