Be careful about wanting what others have. There is always a price. Perhaps God didn’t give it to you, because He knew you wouldn’t be able to pay it.
So often it hurts us that we are not able to focus in our prayers. Remember, the more you focus on Allah outside your salah, the easier it will be to focus on Him inside your salah. What occupies you in salah, is what occupies you outside of salah. Try to fill your mind and heart with Allah as much as you can throughout your day. Talk to Him, make duaa to Him constantly. This will build your personal relationship with Him. Then, going to salah will be like coming home to an old friend.
When someone hurts you, your first thought may be to wish you had never met them at all. But remember that even those who've hurt you, came into your life for a reason, and left for a reason. It’s for the best and healing starts with acceptance.
Hope shouldn’t increase with good deeds and decrease with sin. In good deeds, my hope is for Allah to accept. In sin, my hope is for Allah to forgive.
