The Book of Virtues
Strict Orders for Observance of Obligatory Salat
وَعَنْ جَابِرٍ رَضِيَ اللَّه عَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: إِنَّ بَيْنَ الرَّجُلِ وَبَيْنَ الشِّرْكِ وَالْكُفْرِ تَرْكَ الصَّلاَةِ ((رَوَاهُ مُسْلِم)).
Jabir (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said, "Between a man and disbelief and paganism is the abandonment of Salat (prayer)." [Muslim].
