(a) A similar hadith is reported through another chain. In it there is the addition: just as he used to teach us a surah of the Qur'an; and he said: 'At-tahiyyatu lillah, as-salawatut-tayyibatu lillah'; and at its end he said: 'Nas'alullahal-jannah, wa na'udhu bihi minan-nar' (We ask Allah for Paradise and we seek refuge with Him from the Fire).
(b) Imam Abu Isa al-Tirmidhi (may Allah have mercy on him) says: I asked Imam al-Bukhari (may Allah have mercy on him) about this hadith, and he said: "It is a mistake." The correct version is what al-Layth bin Sa'd narrated from Abu al-Zubayr, from Sa'id bin Jubayr and Tawus, from Ibn Abbas.
Ayman bin Nabil alone narrated it from Abu al-Zubayr from Jabir.
