وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «الصَّلَوَاتُ الْخَمْسُ وَالْجُمُعَةُ إِلَى الْجُمُعَةِ وَرَمَضَانُ إِلَى رَمَضَانَ مُكَفِّرَاتٌ لَمَّا بَيْنَهُنَّ إِذَا اجْتُنِبَتِ الْكَبَائِر» . رَوَاهُ مُسلم

Jabir reported God’s Messenger as saying, “What lies between a man and infidelity is the abandonment of prayer.”* *This means that when a man does not make it his practice to observe the prayer he is no longer a Muslim.Muslim transmitted it.
