Perhaps your heart is rusted because of the sins or your excessive preoccupations with the worldly matters. The solution is not to give up prayer; rather you ought to engage in introspection and remove those barriers or obstacles that prevent you from tasting the sweetness of faith.

Let me cite here from one of my earlier answers posted elsewhere:

 

I must commend you for asking this question. It shows your love of Allah. The answer is at once simple and difficult. It is simple to state, but it is, however, difficult to practice, as we are up against many trials when we do so. The Prophet, peace be upon him, said, ‘hell is paved by things that are pleasing to the carnal soul, while heaven is paved by those things that hard on the carnal soul.” (Al-Bukhari)

 

Let me, however, list some of the ways of enhancing our faith:

 

1) As mentioned in a Hadith Qudsi, in order to increase our iman, we need to be diligent in performing our religious duties, while doing our best to do as much supererogatory acts of worship or virtue that we can;

 

2) Read the Qur’an and seek solace, healing and inspiration in the divine speech. Read it while reflecting on its lessons, and seeking to practice them;

 

3) Keep the role model of the Prophet, peace be upon him, in front of you and try to emulate his beautiful examples;

 

4) Seek to purify your soul of its vices and impurities by engaging in introspection: Ask yourself whether you are guilty of the things which you abhor in others. And see if you have those qualities which you admire in others;

 

5) Keep track of the way you spend your time and energy: Ask yourself if the efforts you are expending energy are worthwhile when you visualize the spectacle of your own death: When all of your life’s work will be played in your mind’s screen as if in a movie;

 

6) Make dhikr (remembrance of Allah) your second habit and keep the company of those who would help you to remember Allah. Avoid friends who would make you heedless of Allah and run away from them as if from a plague;

 

7) Read and reflect on the hadith and the sirah of the Prophet and the life-stories of the salaf al-ssalih (pious predecessors). Reflect on them for inspiration. If possible choose the early morning hours to do so. Imam Ibn al-Mubarak was asked, “Why don’t you entertain visitors in the early morning hours?” He replied, “this is because I choose this time to be in the company of the salaf al-ssalih!” They asked, “They are dead long time ago; so how could you be in their company?” He said, “By reading and reflecting on their life-stories!”

 

I pray to Allah to make us among those who are forever seeking to enhance our iman (faith) to be among those who are chosen by Allah for Himself-amen.

Allah Almighty knows best.
