Tawbah for abandoning Salah

A: The approved opinion of the scholars is that deliberately abandoning the performance of Salah is considered as an act of major Kufr (major form of disbelief), which puts someone outside the pale of Islam. If the person who abandoned the Salah repents to Allah, it is not obligatory on them to make up for the missed Salah nor for the days they did not fast in Ramadan. There is no obligatory Kaffarah for the misdeeds they committed during that period. The person just has to be sincere in their repentance to Allah, Who says: And verily, I am indeed forgiving to him who repents, believes (in My Oneness, and associates none in worship with Me) and does righteous good deeds, and then remains constant in doing them, (till his death). He also says: And those who invoke not any other ilâh (god) along with Allâh, nor kill such person as Allâh has forbidden, except for just cause, nor commit illegal sexual intercourse - and whoever does this shall receive (Part No. 24; Page No. 326)  ...the punishment. The torment will be doubled to him on the Day of Resurrection, and he will abide therein in disgrace; Except those who repent and believe (in Islâmic Monotheism), and do righteous deeds; for those, Allâh will change their sins into good deeds, and Allâh is Oft-Forgiving, Most Merciful. The reality of Tawbah (repentance to Allah) is that someone should regret the past misdeeds they have committed, that they should abandon them totally, and that they should sincerely intend not to do them again, in addition to paying back people's rights.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
