Amr bin Abi Sufyan عمرو بن أبي سفيان بن أسيد · The Book of Faith

Abu Huraira said to Ka'b al-Ahbar that the Messenger of Allah (ﷺ) had said: For every apostle there Is a (special) prayer by which he would pray (to his Lord). I, however, intend (if Allah so willed) that I would reserve my prayer for the intercession of my Ummah on the Day of Resurrection. Ka'b said to Abu Huraira: Did you hear this from the Messenger of Allah (ﷺ)? Abu Huraira said: Yes.
