Some Causes of Poor Health
In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
The Prophet [peace and blessings of Allaah be upon him] said, “The best of the people are those living in my generation, then those who will follow the latter and then those who come after them. Then there will come after them people who will be treacherous and will not be trustworthy, they will bear witness without being asked to do so, and they will vow, but will never fulfil their vows, and fatness will appear among them”. [Saheeh Al-Bukhaari. Number 6695]
Al-Allaamah Rabee Bin Haadi [may Allaah have mercy upon him] said, “They give false testimony, act treacherously and deceitfully. They behave in a very sinful manner and follow evil desires, except those whom Allaah safeguards amongst the Taa’ifatul Mansoorah [i.e. the aided group of Muslims upon the straight path] – those whom Allaah’s Messenger [peace and blessings of Allaah be upon him] praised. Therefore, it is obligated on us to acquire knowledge for the sake of Allaah [The Mighty and Majestic] and act upon it. Ignorance is a deadly disease and knowledge is a weapon that will destroy you if you do not act upon it, and Allaah’s refuge is sought”. [Marhaban Yaa Taalibal Ilm pages 268-270]
Imaam An-Nawawi [may Allaah have mercy upon him] said regarding the statement, “They will bear witness without being asked to do so”, this can mean that they bear witness before being asked, or they bear witness based on falsehood, or they give witness without being from those who are worthy of it”. [Sharh Saheeh Muslim 12/17]
However, there is another Hadeeth in which the Prophet [peace and blessings of Allaah be upon him] stated, “Should I not inform you about the best of witnesses, they are those who bear witness before being asked”. The scholars say that what is intended by this hadeeth is for example: someone has a witness to give on behalf of another person based on truth, but the person does not know about it, so he [i.e. the one who should give the witness] informs the person about it; or for example, a person has already passed away and another person knows what the deceased person has left behind as inheritance, so he bears witness to that and makes it known. [Fat-hul Baari 5/260]
And regarding the statement, “And fatness will appear among them”, Imaam Muhammad Bin Saaleh Al-Uthaymeen [may Allaah have mercy upon him] said, “Meaning, these people give importance to the means of fattening themselves – food, drink and over-abundance. So, their only concern is their bodies and fattening themselves. As for being fat without choice, then one cannot be blamed for that, just as a person cannot be blamed for being tall, short, black or white…”[Majmoo Al-Fataawaa 10/1056]
Imaam Muhammad Bin Saaleh Al-Uthaymeen [may Allaah have mercy upon him] said: The (type) of luxurious lifestyle that exist (today) is that a person does not desire except to drive a comfortable vehicle and to build a spectacular mansion. He does not want to receive any inconvenience – neither (feeling) cold during cold (days) nor the heat during hot (days), nor does he want to be touched by anything, so he (finds) himself in complete luxury. And because of this, health problems such as obesity, high blood pressure and breathlessness is rife amongst them due to a lack of (minimun required) movement (or activity). So, you find some youth climbing a mountain and even before getting halfway, he becomes breathless, (whilst) someone else older than him finds himself in ease, because he [i.e. this older person] is accustomed (to some hardship) but he (i.e. this youth) is not. [Sharh Hilyati Taalibal Ilm. page 40]
