IBNHIBBAN 6466:
from Samiʿah —
[Machine] He heard him say, "I asked the Messenger of Allah, ﷺ , 'O Messenger of Allah, what did your Lord say in response to you about intercession?' He said, 'By the One in whose hand is the soul of Muhammad, I thought that you would be the first to ask me about that from my ummah, because of your keenness for knowledge. What concerns me most is their eagerness to enter Paradise, while I fear that they may fall short regarding the gates of Paradise. What is most important to me is the completion of my intercession for them, and my intercession for those who bear witness that there is no god but Allah sincerely, and that Muhammad is the Messenger of Allah, with sincerity from both their tongue and heart.'"

عن سمعه —
أَنَّهُ سَمِعَهُ يَقُولُ سَأَلْتُ رَسُولَ اللَّهِ ﷺ قُلْتُ يَا رَسُولَ اللَّهِ مَاذَا رَدَّ إِلَيْكَ رَبُّكَ فِي الشَّفَاعَةِ؟ قَالَ «وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَقَدْ ظَنَنْتُ أَنَّكَ أَوَّلُ مَنْ يَسْأَلُنِي عَنْ ذَلِكَ مِنْ أُمَّتِي لِمَا رَأَيْتُ مِنَ حِرْصِكَ عَلَى الْعِلْمِ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَمَا يُهِمُّنِي مِنَ انْقِصَافِهِمْ عَلَى أَبْوَابِ الْجَنَّةِ أَهَمُّ عِنْدِي مِنْ تَمَامِ شَفَاعَتِي لَهُمْ وَشَفَاعَتِي لِمَنْ شَهِدَ أَنْ لَا إِلَهَ إِلَّا اللَّهُ مُخْلِصًا وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ يُصَدِّقُ لِسَانُهُ قَلْبَهُ وَقَلْبُهُ لِسَانَهُ»
