In one narration the words are: "The Highest Companion, who is the most blessed."
Ahmad and al-Tabarani in al-Mu'jam al-Awsat recorded it, except that they recorded these words: Sayyidah Aishah (may Allah be pleased with her) narrates: The Prophet (peace and blessings be upon him) passed away between my neck and my chest. Sayyidah Aishah (may Allah be pleased with her) says: I thought that Allah Almighty would return his soul to him. Sayyidah Aishah (may Allah be pleased with her) says: That is how it is done with the prophets. Then the Prophet (peace and blessings be upon him) moved, and I thought: Even if you are given the choice today, you will not choose us. The narrators of one of Ahmad's two chains are the narrators of the "Sahih".
