Who is the founder of the the Shadhiliyya Qadiriyya Tariqa, where is it widespread, and does it have a website?

The Shadhiliyya Tariqa is one of the Sufi orders, founded by Abul-Hasan al-Shadhili. It is widespread in Egypt and some Arab countries. This Tariqa is based on the Sufi thought prevalent today. The questioner is advised not to preoccupy himself with it, but rather to seek knowledge from the Quran and Sunnah, according to the understanding of the righteous predecessors of the Ummah. However, if the questioner is among the well-established students of knowledge, he may review their books, study their ideas, and evaluate them by the scale of the Shari'ah.
