I came in the deputation of Banu al-Muntafiq to the Messenger of Allah ﷺ. He then narrated the rest of the tradition. The Prophet ﷺ said: la tahsibanna (do not think) and did not say: la tahsabanna (do not think).
كُنْتُ وَافِدَ بَنِي الْمُنْتَفِقِ أَوْ فِي وَفْدِ بَنِي الْمُنْتَفِقِ إِلَى رَسُولِ اللَّهِ ﷺ فَذَكَرَ الْحَدِيثَ فَقَالَ يَعْنِي النَّبِيَّ ﷺ لاَ تَحْسِبَنَّ وَلَمْ يَقُلْ لاَ تَحْسَبَنَّ
