[Machine] The Prophet ﷺ said, "Cursing a believer is like killing them. And whoever declares a Muslim as disbeliever, it will return upon one of them." Abu al-Qasim said, "Abu Abdullah, also known as Khalid al-Hadha', has two titles: Abu Munazil and Abu Abdullah."
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «لَعْنُ الْمُؤْمِنِ كَقَتْلِهِ وَمَنْ أَكْفَرَ مُسْلِمًا فَقَدْ بَاءَ بِهَا أَحَدُهُمَا» قَالَ أَبُو الْقَاسِمِ «أَبُو عَبْدِ اللهِ هَذَا يُقَالُ لَهُ خَالِدٌ الْحَذَّاءُ وَخَالِدٌ لَهُ كُنْيَتَانِ أَبُو مُنَازِلٍ وَأَبُو عَبْدِ اللهِ»
