Today Muslims should set the example for all of Mankind. I believe non-Muslims expect a lot of morals from Muslims. That is why they attach Islam to every Good and Evil thing that is done from Muslims, because they think that we live our lives 100% by the laws of Islam.
So, when Muslims go frequently to casinos, then they are not really helping themselves to allow Allah Almighty to help them “prosper”, and they are not giving the good impression about Islam.
Muslims should build a personal friendship and relationship with Allah Almighty:
We have to understand that Islam is not all about fearing Allah Almighty. Yes of course we have to fear Him, but Islam is also about respecting Allah Almighty and building that personal friendship and relationship with Him. If you respect Allah satta king Almighty and respect His likes and dislikes in life, then He will become your personal friend, and He will always be there for you to make you feel better through His Holy Spirit, and to inspire you to make the right things and decisions:
“Who can be better in religion than one who submits his whole self to God, does good, and follows the way of Abraham the true in Faith? For God did take Abraham for a friend. (The Noble Quran, 4:125)”
“(O Muslims) Your (real) friends are Allah, His Messenger [Muhammad], and the (Fellowship Of) Believers, those who establish regular prayers and regular charity, and they bow down humbly (in worship). (The Noble Quran, 5:55)”
How can a person be a gambler and Allah Almighty’s friend at the same time? It’s impossible. So until we change what’s inside of us and make ourselves better people in everything we do to please Allah Almighty with our righteous work, Allah Almighty will never help us, because He said:
“Because God will never change the grace which He hath bestowed on a people until they change what is in their (own) souls: and verily God is He Who heareth and knoweth (all things). (The Noble Quran, 8:53)”
Conclusion:
Gambling is a bad thing and Satan’s work, because it causes the person to gain a “great sin” and to not “prosper”. Allah Almighty commanded the Muslims to stay away from it. If a Muslim wishes to build a personal friendship and relationship with Allah Almighty, then he/she must thrive to do righteousness and to always be the best example to both Muslims and non-Muslims.
