Imam Badr al Din al Ayni Hanafi on Wajd of Sufis.
It is strange that they claim that they Love Allah and goes against the Sunnah of Prophet peace be upon him, because they clap, sing songs, scream and They swoon (faint) themselves. All that is their ignorance. Whoever claim to Love Allah and go against sunnah of Prophet peace be upon him is a liar. Quran considers him a liar.. They make Ishqiya picture in their heart, corrupt it and claim that they are in great wajd, they cry badly and do different things. They say things from their tongue.. The ignorant people have aiteqaad over them, take their companionship and attribute themselves to them.. They only follow false claims and sayings. May Allah save us from their shar and the shar of jinns and people.
