Abaprofethi yizidalwa eziphakeme kakhulu ezikhethwe nguNkulunkulu ukuba zikhombise abantu indlela eyiyo futhi zibafikisele imiyalo kaNkulunkulu. Umprofethi ngamunye ubonisa izimangaliso njengobufakazi kubantu bakubo. Izimangaliso yizenzakalo ezinkulu nezingavamile ezingachazwa ngemithetho yemvelo, futhi zenzeka kuphela ngemvume kaNkulunkulu. Lesi sigaba sibhekisisa izimangaliso ezaboniswa abaprofethi, incazelo yalezi zimangaliso ku-Islam, nokuthi ngasinye isingamiso sibhekwa kanjani njengophawu olusekelayo umsebenzi womprofethi.

I-Qur’an eNgcwele ikhuluma ngezimangaliso zabaprofethi abaningi. Ngokwesibonelo, izimangaliso ezinjengokuhlukanisa ulwandle kabili kukaMusa (a.s.), ukuvusa abafileyo kukaJesu (a.s.), nokwenyukela eMiraj kukaMuhammad (asm) yizibonakaliso ezinkulu ezifakazela ukuthi abaprofethi bangabathunywa bakaNkulunkulu. Isimangaliso ngasinye sibonisa ubuqiniso bomprofethi futhi siyisibonakaliso sokuthi uthunywe nguNkulunkulu.

Izimangaliso azigcini nje ngokuba yizenzakalo ezibonisa amandla angavamile, kodwa futhi yizenzakalo eziqinisa ukholo lwabantu futhi ziqinisa ukukholwa kwabo kuNkulunkulu. Kulesi sigaba, kunikezwa ulwazi olunzulu ngezimangaliso zomprofethi ngamunye, izincazelo zalezi zimangaliso ezingagciniwe isikhathi nendawo, nokuthi lezi zimangaliso kufanele ziqondwe kanjani esikhathini samanje.
