In one narration the wording is: "Every fair-skinned or dark-skinned person who enters my Ummah will be counted among them."
Imam Ahmad and al-Bazzar recorded it, and al-Tabarani recorded something similar, except that he narrated these words: "So much so that the enemy feels fear of me from a distance of a month or two months (the narrator is in doubt), and it was said to me: Ask and you will be given, so I kept my supplication in reserve as intercession for my Ummah." Imam Ahmad's narrators are the narrators of the Sahih, except Yazid bin Abi Ziyad, and he is hasan al-hadith (good in hadith).
