He mentioned that a Non-Muslim woman moved to a Muslim country for some business purposes. As she stayed among the Muslims and saw their lifestyle, she was impressed and wanted to learn more about Islam. As a result, she started borrowing books from the local library about Islam. A Muslim lady in the library used to ask her often if she was convinced to become a Muslim yet. She would reply that the time hasn't come yet. One day as she got some books from the library and was walking back home, the iqamah for coming to the prayer was called in a masjid across the road. She observed that a person who was sweeping the floor had left his work and stood on the line to pray and right beside him stood a rich man who came to the masjid driving a very expensive car. At that moment, she decided to become a Muslim as she was greatly impressed by seeing that in Islam there is no difference between the rich and the poor when they stood in front of Allah.
"O mankind! We have created you from a male and a female, and made you into nations and tribes, that you may know one another. Verily, the most honourable of you with Allah is that (believer) who has At-Taqwa [i.e. one of the Muttaqun (pious)]. Verily, Allah is All-Knowing, All-Aware." Holy Quran, Surah Al-Hujuraat, 49:13
