عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ: ((بَيْنَ الْعَبْدِ وَبَيْنَ الْكُفْرِ أَوِ الشِّرْكِ تَرْكُ الصَّلَاةِ))
It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Between a servant and disbelief or polytheism is the abandonment of prayer.
