The inherent permissibility or impermissibility of some of these exercises will rest upon the differences of the various Madhāhib since some of these practices cross the boundary of a mere internal metaphysical sphere to the externally physical; thus, falling under the jurisdiction of the Fuqahā’. To present a brief example, the practice of hadrah, a type of spiritual bodily movement similar to swaying that some refer to dancing coupled with loud dhikr, is permissible for the followers of the Shāfi‘ī Madhhab since according to their ‘Ulamā and Madhhab dancing is permissible with certain conditions.

والرقص بلا تكسر مباح لخبر الصحيحين إنه صلى الله عليه وسلم وقف لعائشة يسترها حتى تنظر إلى الحبشة وهم يلعبون ويزفنون والزفن الرقص لأنه مجرد حركات على استقامة أو اعوجاج وعلى الإباحة التي صرح بها المصنف الفوراني والغزالي في وسيطه وهي مقتضى كلام غيرهما وقال القفال بالكراهة وعبارة الأصل محتملة لها حيث قال و الرَّقْصُ ليس بِحَرَامٍ وَبِالتَّكَسُّرِ حَرَامٌ وَلَوْ من النِّسَاءِ لِأَنَّهُ يُشْبِهُ أَفْعَالَ الْمُخَنَّثِينَ (أسنى المطالب في شرح روض الطالب ج 4 ص 346 العلمية)


Consequently, it will be permissible for the Shuyūkh and Mūrīds who follow the Shāfi‘ī Madhhab to participate in the hadrah. On the contrary, it will not be permissible for the Shuyūkh and Murīds of the Hanafī Madhhab to participate in the dancing or swaying of the hadrah since no form of dancing is permitted in the Madhhab unless one is overtaken by an uncontrollable state of ecstasy.
