There is another narration on the same theme attributed to the Prophet
Mohamed where he is reported to have said the following;
عن زيد بن أسلم عن بن عمر رضى ﷲ تعالى عنھما قال قال النبي
صلى ﷲ عليه وسلم رأيت غنما كثيرة سوداء دخلت فيھا غنم كثيرة

وأنسابكم قالوا العجم يا رسول ﷲ قال لو كان اإليمان معلقا بالثريا
لناله رجال من العجم وأسعدھم به الناس. ھذا حديث صحيح على

They will accept Islam and become so many that the Arabs will not be noticed

"I saw a group of black sheep and a group of white sheep then mixed with the
black sheep. I interpreted it to mean that the non-Arab Persians will enter Islam
and then share with you your genealogy and your wealth."
The companions became surprised by what he said. Then one said,
"The non-Arab Persians will enter our land, Oh Messenger of Allah?!" The Prophet
then said, "Yes. By He Who Has my soul in His Hand, if the religion was hanging
