There is no limit to universality in Islam. The universality of Islam is unlimited. When the Prophet was migrating from Makkah to Madinah, the journey was not similar to the roads and highways of today. There were jungles and mountains in the path. Not every person knew the path from one place to another. Only some people knew the way. This was a family profession. People would get trained in this. They would then stand in the path to guide people. The Prophet needed a guide to travel from Makkah to Madinah. The guide that the Prophet chose was Abdullah ibn Urayqit or Abdullah ibn Arqat. He was a Makkan polytheist and didn’t yet believe in the Prophet. This journey was very difficult and treacherous. In this journey, the Prophet took Abdullah ibn Arqat as his guide. This shows that there is no limit to Islam's universality. 
The hadith says: الْكَلِمَةُ الْحِكْمَةُ ضَالَّةُ الْمُؤْمِنِ، حَيْثُمَا وَجَدَهَا فَهُوَ أَحَقُّ بِهَا (Sunan ibn Majah 4169)

Wisdom may come from Muslim or non-Muslim, Asian or European, black or white. You don’t need to see who the speaker is. You only need to take in wisdom from people. The Prophet not only said take wisdom but also said that wisdom is the lost property of the believer, wherever he finds it he must accept it. If I drop my pen somewhere, I will return to find it. If I find the pen, it will be mine and I will take it back happily.  In the same way, if you find wisdom anywhere you have to happily accept it. One shouldn’t think that this isn’t coming from people of my community. There is no concept of us and them in Islam. Wisdom is a universal asset. It belongs to all. It is not that it belongs to one and not to another. It is for all.
