Repent if You Have Sinned for Allah (SWT) is the Most Merciful
The first and foremost thing that a person has to do who wishes to live a happy life in this world and find success in the next is to ask for forgiveness from Allah (SWT) and worship him. Allah (SWT) has blessed us all with a very invaluable gift, which is Dua. Dua is a means from which Allah (SWT) has directly opened a door for us to get in touch with him and ask for his forgiveness or ease in affairs or anything.
The Quran is the word of Allah (SWT) Himself that was revealed to Prophet Muhammad (SAW) centuries ago. In the Quran are recorded all the rules and guidance that if followed can lead a person to success in this life and the next. Reading the Quran is one of the proven and best ways to release anxiety and stress and it brings one closer to Allah (SWT) and softens the heart. People who do not have access to good teachers should really consider joining an online Quran school or get the services on an online Quran teacher through whom they can learn at their own pace and timings.
