Assalamo alaikum wa rahmatullahi wa barakatuhu
Im not friends with any people who pray or fast...most of my friends are like me
The root of your problem is the type of company you are in. If you are in the company of pious people, you will naturally want to be religious as well, and you will experience a living Islam. But if you are in the company of the riff raff, and you try to practice your religion, it is only natural it would seem futile to you. It would seem that your religion is of no use to you, especially since all of your friends have nothing to do with it.
Say: "I will not follow your wain desires: If I did, I would stray from the path, and be not of the company of those who receive guidance." (6:56)
Your claim that you see nothing useful about religion, and that it only breeds hate and violence is your psychological justification for becoming unrighteous. When people feel guilty about something, they will naturally try to justify their behavior somehow.
So my sincere advice to you is to leave the company of those people who are harming your faith, and you start making friends with the pious people. Insha Allah, you will find that they are much more friendly and accepting, and they are not "artificial" either, they will care about you and make your life much healthier and better.
It's never to late, the doors of repentence are always open.
There are seven keys to answered prayer:
To worship Allah, offering Him sincere devotion, being true (in faith) (98:5)
#1 pray sincerely and fervently to Almighty Allah. pray to Him for each and every of your need. Do not feel shy, ask Him for EVERYTHING you need, become totally dependent on Him through salaat. Remain true to His cause and to the Faith, and offer Him any and every sacrifice which you are called to do.
These are the Ayats of Revelation, of a Qur'an that makes things clear (15:1)
#2 Study the Holy Quran regularly and consistently, do independent study as well as attend dars Quran classes in your local masjid or jamaat. Studying the Holy Quran will give you greater understanding and wisdom, and will thus increase your faith and draw you nearer to your Lord above.
Then He turned to them, that they might repent: for Allah is Oft-Returning, Most Merciful (9:118)
#3 Repent of your past sins and lifestyle. Amend your evil ways, and begin a new life as a religiously observant Muslim. Every now and then people fall and go astray, but you must resolve to refresh your life and return to the Straight Path. Do not go further down the pit of doom, but once you have realized your peril, begin to climb up toward the light.
For these, there is hope that Allah will forgive: For Allah doth blot out (sins) and forgive again and again (4:99)
#4 Forgive other people what they have done to you, and become humble. If you want Allah Taala to forgive you and begin a fresh relationship with you, you must do the same with others.
And in Allah should the faithful (Ever) put their trust (3:122)
#5 Have absolute and unconditional faith in Allah. No matter how ugly the situation may be, never lose hope or faith in the promise of Allah. Never believe for a second that He will not come to your rescue when you need Him.
And be steadfast in prayer; practise regular charity; and bow down your heads with those who bow down (in worship). (2:43)
#6 Be consistent in your worship, pray five times a day daily. If you are consistent in your prayers, and not erratic, you will find Allah will answer your prayers and He will manifest His favour in your life very clearly. Also, give frequent charity and alms for the cause of Allah. Do not become attached to money, but derive joy from spending it for the sake of strengthening your faith.
Then do ye remember Me; I will remember you. Be grateful to Me, and reject not Faith (2:152)
#7 Praise Allah and be grateful for what you already have. Become happy and not gloomy, and sing the praises of Allah for each and every little, as well as big thing, that helps you.
