 why do we pray 5 times a day

why do we pray 5 times a day

By: Ahmed Rehab Why Do We Pray 5 Times a Day? For many reasons, but one simple reason is this: prayer is the sump pump to our sins. Since the sins are invariably guaranteed to keep coming, so must the sump pumps keep working. Groundwater is a consequence of rain, and sin is a consequence of life. Regulated sump pumps protect, and so does regular prayer. Allah states that when you perform your prayer, it erases all sins accumulated since your last prayer. Kind of like how the sump pump eliminates the dirty water, your sins are erased. Our first precaution against sin is to try our best to shelter ourselves from it, no doubt. My home s first line of defense against rain damaging its valuable contents is the roof and walls that provide shelter. I could not have a roof-less, wall-less house

 why is copper used in water pipes

why is copper used in water pipes

If the plumbing in your home is old, it is likely that your water pipes are made from iron, steel, or lead. Modern water pipes are almost always made from copper, although plastic or polyvinyl chloride (PVC) pipes are becoming popular too. You should consider replacing old iron pipes with modern copper or PVC pipes, and lead water pipes should certainly be replaced. Copper and PVC water pipes are relatively non-toxic. Copper is a natural material that has been proven to be safe to health. PVC pipes are also safe. Lead on the other hand is extremely toxic. Lead is corrosive and can leak into the drinking water system. Exposure to lead can lead to a range of health problems and eventually end in death. Lead cannot be removed once it gets into a person's system. Copper is non-permeable. It

 why is physics important in everyday life

why is physics important in everyday life

Any sort of technology which we uses in our daily life is related to Physics. Physics is the science of matter and its motion, space-time and energy. Physics describes many forms of energy - such as kinetic energy, electrical energy, and mass; and the way energy can change from one form to another. Everything surrounding to us is made of matter and Physics explains matter as combinations of fundamental particles which are interacting through fundamental forces. It will not be an exaggeration if it is said that Nature is almost Physics (apart from the fact that the word Physics itself is derived from Greek "physis" meaning nature). Physics is all around us. We can find Physics as the backbone for any daily life example such as an electric light, electricity, the working of our vehicle,

 why do the elderly fall asleep all the time

why do the elderly fall asleep all the time

Syncope is defined as a self-limited loss of consciousness, usually combined with falling due to the inability to maintain postural tone. The underlying mechanism is a transient global cerebral hypoperfusion. The aetiology essentially includes cardiac disorders (structured heart disease or arrhythmias), neurally-mediated reflex syndromes, orthostatic hypotension and carotid sinus syndrome. History and physical examination will lead to the diagnosis in up to 50% of cases [ ]. In patients with arrhythmic syncope, a poor prognosis can be expected if syncope is misdiagnosed, particularly when arrhythmias occur in a patient with advanced heart disease [ ]. The most important step is to differentiate patients with heart disease from others, since the mortality of these patients is doubled [ ].

 why do we need protein in our body

why do we need protein in our body

Antibodies are proteins that are important for immunity. When harmful viruses and bacteria, called antigens, invade your body, antibodies destroy them. This protects you from sickness and disease. Proteins exist as hormones, regulating specific body processes. Hormones are carried by the bloodstream to a particular site in the body that needs regulation. For example, in response to varying blood sugar levels, the hormone insulin is released, which helps to regulate and maintain proper energy utilization. Proteins also play important roles in blood clotting and vision. Additionally, they help proteins regulate the acid-base balance in the body by acting as buffers. Proteins function as enzymes, facilitating chemical reactions in the body, such as the breakdown or build up of substances in

 why do we need to eat fat

why do we need to eat fat

Fat has many uses within our bodies which without it, we wouldnвt be alive. All too often you hear another infomercial talking bad about fat again. What they donвt realize is that fat has many powerful uses and without it those infomercialsВwouldn tВeven be shown. Reason #1 Fat provides us with a huge source of energy. This energy would be almost unattainable eating just protein and carbs alone. Think about it this way, for every gram of fat you eat you get 9 calories of fuel for your body. Carbohydrates and proteins only get 4 calories for every gram that is eaten. Once we expend all of our carbohydrates in our body, fat comes to the rescue as an energy source. Without it our bodies start literally eating themselves and breaking down tissues such as muscle. So fats are essential to

 why do people wear black in the desert

why do people wear black in the desert

It s just a generalized description Sim. All fabrics will be transparent if thin enough, but black materials less than white, due to the way they can absorb and transform the visible radiation to heat. Then white thick cotton is better than black thick cotton. Not if you want the convection, then black should be what you aim for. White reflects light of all wavelengths whilst a red cloth absorbs all other colors than red better, how good it absorbs those other will be seen as how red the cloth will be to you, also depending on the light-source of course. Black also reflects all colors, just like white, but as it absorbs so much of them the net effect becomes a black. That I didn t mention it before was because I was trying to keep to what the main question was why do people wear black in
