Clarifying the usage of the word Kafir for one who abandons Salat
حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا الأَعْمَشُ، بِهَذَا الإِسْنَادِ مِثْلَهُ غَيْرَ أَنَّهُ قَالَ " فَعَصَيْتُ فَلِيَ النَّارُ " .
A'mash narrated this hadith with the same chain of transmitters, with this change of words that he (the Satan) said: I disobeyed and I am doomed to Hell.
