that the Prophet ﷺ said: "Between disbelief and faith is abandoning the Salat."  

أَنَّ النَّبِيَّ ﷺ قَالَ بَيْنَ الْكُفْرِ وَالإِيمَانِ تَرْكُ الصَّلاَةِ  

Similar to the previous chain and said: "Between a slave and Shirk or disbelief is abandoning the Salat."  

وَقَالَ بَيْنَ الْعَبْدِ وَبَيْنَ الشِّرْكِ أَوِ الْكُفْرِ تَرْكُ الصَّلاَةِ  

that the Messenger of Allah ﷺ said: "Between a slave of Allah and disbelief is abandoning the Salat."  

قَالَ رَسُولُ اللَّهِ ﷺ بَيْنَ الْعَبْدِ وَبَيْنَ الْكُفْرِ تَرْكُ الصَّلاَةِ  

that the Messenger of Allah ﷺ said: "The covenant between us and them is the Salat, so whoever abandons it he has committed disbelief."  

قَالَ رَسُولُ اللَّهِ ﷺ الْعَهْدُ الَّذِي بَيْنَنَا وَبَيْنَهُمُ الصَّلاَةُ فَمَنْ تَرَكَهَا فَقَدْ كَفَرَ وَفِي الْبَابِ عَنْ أَنَسٍ وَابْنِ عَبَّاسٍ  

The Companions of Muhammad ﷺ didn't consider leaving anything to be disblief except for the Salat.  

كَانَ أَصْحَابُ مُحَمَّدٍ ﷺ لاَ يَرَوْنَ شَيْئًا مِنَ الأَعْمَالِ تَرْكُهُ كُفْرٌ غَيْرَ الصَّلاَةِ
