The ruling on one who abandons prayer

عَنْ جَابِرٍ، قَالَ قَالَ رَسُولُ اللہِ صَلَّی اللہُ عَلَیْہِ وَسَلَّمَ لَیْسَ بَیْنَ الْعَبْدِ وَبَیْنَ الْکُفْرِ اِلَّا تَرْکُ الصَّلَاۃِ

Hazrat Jabir^ra narrates, “The Holy Prophet^sa said, ‘There is nothing between a person and disbelief except abandoning Salat.’”

(Sunan Nasa‘i, Kitab al-Salat, Hadith 464)
