Q: What is the ruling on a man who abandons Salah (Prayer) for a long period of time then repents to Allah (Exalted be He) and resumes Salah at their due times regretting the acts of obedience he missed? However, he does not stick to this obedience.

(Part No. 6; Page No. 47)  A: If a person intentionally abandons Salah because of denying its obligation, he is a disbeliever according to Ijma` (consensus) of religious scholars. If a person abandons Salah because of negligence or laziness, he is also a disbeliever according to the authentic view of religious scholars. However, if the person repents to Allah (Exalted be He) and offers Salah, he is considered a Muslim. Indeed, repentance wipes out past sins and Islam wipes out the evil deeds that were committed before it. This person then does not have to make up for the missed Salahs; however, it is obligatory for him to commit himself to Salah and keep praying to Allah (Exalted be He) for help and success in achieving this. This is because the Prophet (peace be upon him) said: Verily, the hearts are between two of the Fingers of the Most Merciful. He turns them however He wills. May Allah guide him to the truth and protect him from evils, devils, and whims.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
