Getting in touch with ALLAH

 Happiness is a state that can be termed as a mental state in which a person is positive or feels pleasant. Every human being on this earth pursues happiness in this world. It doesn’t matter if you are a child, adult, Muslim or Non-Muslims; the pursuit of happiness is a universal goal. There are various scientific researches that categorize happiness based on specific things. An Islamic perspective to achieving happiness is simply being content with what one has in life. This simply means that if a believer has true faith in Allah (SWT) and complete trust in Him, than he is satisfied with what he or she has in life and is happy. Prophet Muhammad (SAW) emphasized on the importance of being content with ones lot in life in various duas such as:

 “I am pleased with Allah as my Lord, with Islam as my religion, and with Muhammad as my Prophet (peace and blessings be upon him).” [Abu Dawud]
 “O Allah, make me content with what you have provided me, send blessings for me therein, and place for me every absent thing with something better.” [Bukhari]
 “O Allah, I seek refuge with You from knowledge which does not bring benefit and from a heart which is not fearful and from a self which is not content and from a supplication which is not answered.” [Muslim]
One thing to make sure is that happiness can never be found in money and materialistic pursuits and things, rather it comes from the remembrance and faith in Allah (SWT). Here are some ways to be happy in life.
Striving to Earn the Pleasure of Allah (SWT)
There is no other way, period that is more relevant and rewarding that results in direct happiness than seeking the favor and pleasure of Allah (SWT). Allah (SWT) Himself tells us in the Quran about who deserve the supreme success.
The believers, men and women, are Auliyâ' (helpers, supporters, friends) of one another; they enjoin (on people) Al-Ma'rûf (good), and forbid (people) from Al-Munkar (evil); they perform As-Salât (prayer), and give the Zakât (charity), and obey Allah (SWT) and His Messenger. Allah (SWT) will have His Mercy on them. Surely Allah (SWT) is All-Mighty, All-Wise. Allah (SWT) has promised the believers -men and women, – Gardens under which rivers flow to dwell therein forever, and beautiful mansions in Gardens of 'Adn (Eden Paradise). But the greatest bliss (happiness) is the Good Pleasure of Allah (SWT). That is the supreme success. 
(Quran Surah Al-Tawbah Ayahs 71-72)
Eat Good Clean Halal Food
Halal food eating is ordained by Allah (SWT) on the believers. Earning and eating halal is a way to please Allah (SWT) and the pleasure of Allah (SWT) leads to ultimate happiness. 
Abu Hurairah(RA) related,” Allah (SWT)’s Messenger PBUH said: Verily Allah is pure and He accepts only what is pure and indeed Allah (SWT) has given those orders to the believers, which he has given to the Messengers. He has said, “O Messenger, eat from the pure foods and work righteous”. He -also- has said: “O you who have believed, eat from the pure things which we have provided you.” Then (the Prophet SAW) made mention of a man who undergoes a lengthy journey in a state that he is disheveled and dusty. He spreads his hands towards the sky (calling), “O my lord, O my lord”, however his food is haram, his drink is haram, his clothes are haram and he has been nourished with haram! So how will his call be answered?” [Muslim]
Along with spiritual guidance and nurturing, Muslims and all people for that matter must and should focus also on physical nurturing of their bodies to the best of their abilities. Scientists hold consensus on the fact exercising actually makes humans happy. It is one of the most important anti-depressants described by doctors to people suffering from anxiety and depression. Prophet Muhammad (SAW) said,
“The strong believer is better and more beloved to Allah (SWT) than the weak believer, while there is good in both.” [Muslim]
