All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
So long as you know that the Prayer is an important pillar of Islam and that abandoning it is Kufr (disbelief), then you should put forward to yourself the following question:
Who is stopping and obstructing me from performing my Prayer? You will find the answer immediately without delay or doubt, that it is Satan (the devil), since he is the enemy of the believers, as Allah Says (what means): {Indeed, Satan is an enemy to you; so take him as an enemy. He only invites his party to be among the companions of the Blaze.} [Quran 35: 6]
Satan has many tricks and methods in approaching the son of Adam and leading him astray; Allah Says (what means): {[Satan] said, "Because You have put me in error, I will surely sit in wait for them on Your straight path. Then I will come to them from before them and from behind them and on their right and on their left, and You will not find most of them grateful [to You]."} [Quran 7: 16-17]
If this is the case, then how can it come across a sane person's mind, let alone a believer, to chase the trails of the footsteps of his enemy who wants to deceive him and entrap him into Hellfire?
Therefore, the means you should take to save yourself from his traps and deception is to seek refuge in Allah from Satan, and then to seek Allah's Help against him, as Allah Says (what means): {So when you recite the Qur'an, [first] seek refuge in Allah from Satan, the expelled [from His mercy]. Indeed, there is for him no authority over those who have believed and rely upon their Lord. His authority is only over those who take him as an ally and those who through him associate others with Allah.} [Quran 16: 98-100]
We advise you to frequently observe the remembrance of Allah, to say the morning and evening supplications, as well as the supplications that are to be said before going to sleep and when wakening up in the morning.
Furthermore, we also advise you to listen to audio tapes and attend talks where one is encouraged and inspired to keep steadfast in performing his Prayer punctually, as well as taking righteous sisters as your company since they could be great help to you in boosting your Iman and motivating you.
Finally, we recommend that you inform your husband about this since he may give you a helping hand and some solutions.
