"What is the matter with you, then, that you have become two factions regarding the hypocrites?" Muhammad said: "Two factions" is in the accusative case (mansub) as a circumstantial qualifier (hal). The meaning is: What is the matter with you in [your] disagreement concerning their affair? "And Allah has cast them back [to disbelief] for what they earned." They were a people from the hypocrites who were in Medina, then they left it for Mecca, and then they left from Mecca to al-Yamamah as merchants; they apostatized from Islam and revealed what was in their hearts of polytheism. The Muslims encountered them, and regarding them, [the Muslims] became "two factions"—meaning: two groups. Some of them said: "Their blood has become lawful; they are polytheists and apostates."
﴿فَمَا لَكُمْ فِي الْمُنَافِقِينَ فِئَتَيْنِ﴾ قَالَ مُحَمَّد: ﴿فئتين﴾ نصب على الْحَال الْمَعْنى: أَي شَيْء لكم فِي الِاخْتِلَاف فِي أَمرهم؟ ﴿وَاللَّهُ أَرْكَسَهُمْ بِمَا كَسَبُوا﴾ هُمْ قوم من الْمُنَافِقين كَانُوا بِالْمَدِينَةِ؛ فَخَرجُوا مِنْهَا إِلَى مَكَّة، ثُمَّ خَرجُوا من مَكَّة إِلَى الْيَمَامَة تجارًا فَارْتَدُّوا عَنِ الْإِسْلَام، وأظهروا مَا فِي قُلُوبهم من الشّرك، فَلَقِيَهُمْ الْمُسلمُونَ، فَكَانُوا فيهم (فئتين - أَي:)) فرْقَتَيْن - فَقَالَ بَعضهم: قد حلت دِمَاؤُهُمْ؛ هُمْ مشركون مرتدون،
