who were the sufis
Sufis are Muslims, hence, their God is Allah.
This is a false dichotomy. There are Sunnis who are Sufis and there are Sufis who are Sunnis. There are Sunnis who are not Sufis and there are Sufis who are not Sunnis. Being a Sunni means to follow the Prophet Muhammad (SAW) and his blessed sunnah. Being a Sufi means to be even more strict in following this sunnah in an effort to rectify yourself spiritually. Many people claiming to be Sufis are in fact, NOT Sufis if they deviate from the sunnah. Many popular scholars from the past and present have been Sufis. Ibn Taymiyyah, Imam Ghazali, etc. have all been Sufis and Sunnis.
