Hazrat Sheikh Abdul Wahid bin Zayid ra narrates
a meeting with a Chinese rahib (ascetic) who gave the reason for his seclusion (khalwa) as:
“I am like a ferocious dog that tears up everyone who comes near!
To prevent myself from tearing others apart with my speech
I have confined my self in this monastery.”
Imam Yafai’i ra’s Raudhul Rehyaheen/Nuzhatul Basateen page # 320.
