I was captured reading the email and here are some lines which make me thinking and later I browsed the websites looking for articles of what happiness means in Islam.
"Being Happy is an attitude about life and each one of us must decide"
"Being Happy depends on you!"
I agree. It is very much depends on you. It is the way you perceive yourself. You want to enjoy your existence in this world..then perhaps you should try told be happy..If you think that the world is unfair to you..and you choose to be sad..then..that's it. You will be sad forever. Allah is always fair. And each one of us will have our fair share of sadness and happiness. Its a part and parcel of being you..a mere human being who is always under Allah's Qadaq and Qadar.
As most of us have come to realise, happiness is that ethereal quality that encompasses contentment and peacefulness; it is the soft joy that causes our lips, faces and hearts to smile. It is determined by faith in God and obedience to Him. Thus happiness embodies the peace security and submission that is Islam. The injunctions and regulations of Islam reinforce the happiness that comes from knowing God and they help to guarantee humankind’s happiness during life in this world. However, Islam also emphasizes that the life of this world is nothing more than a means of attaining the Hereafter. By following the guidelines of Islam it is possible to be happy while awaiting our eternal happiness.
Sometimes, in order to achieve happiness, people attempt to follow complicated paths; they fail to see the easier path that is Islam. Happiness can be found in the solace that comes from being upon the truth. It can be achieved by sincere worship, hastening to do virtuous, noble and beautiful deeds, and by performing acts of kindness or giving charity. These things all have the potential to make us happy, every day, under any circumstances. Even giving the smallest charity, in order to please God, can bring a smile to your face and a feeling of joy to your heart.
“And the likeness of those who spend their wealth seeking God’s pleasure while they are sure and certain that God will reward them (for their spending in His Cause), is the likeness of a garden on a height; heavy rain falls on it and it doubles its yield of harvest. And if it does not receive heavy rain, light rain suffices it.” (Quran 2:265)
