To know how the Egyptians can be affected by religion, you need to visit some old mosques in Islamic Cairo. One of the famous examples that can show you this is Al-Sayeda Nafeesah Mosque, and many Egyptians believe in its importance.
Nafeesah was a woman who was one of the descendants of the Prophet Mohamed. She travelled from Makkah to live in Egypt and Egyptians used to visit her frequently to ask her about Islamic issues. After her death in 824, she was buried in Cairo and they built this mosque to commemorate her.
Now, after all these years, Egyptians still go to her to pray and ask help for their needs. I was totally amazed by the shape of the golden shrine with dozens of people surrounding it.
Inside the mosque, I sit for a while in the inner courtyard to listen to the Sufi songs and to watch the sun perpendicular to the minaret.
Whenever you go there, you need to be ready to deal with the crowds outside and inside the mosque.
