although a practitioner of sufism, ghumari was a strong critic of many sufis, especially the rival naqshbandi order. like ibn hazm, ghumari viewed scholarly difference of opinion as a curse. like his brothers, he often used harsh language when responding to intellectual opponents. having originally followed the maliki school of thought like most of muslim scholarship in morocco, al-ghumari later switched to the shafi'i school for a period and finally opted for absolute independent reasoning. unlike most of moroccan scholarship, al-ghumari opposed the ash'ari school of theology. muhammad abu khubza, among other moroccan scholars, also claim that al-ghumari temporarily adhered to the zaidiyyah school of shia islam.
