Hadithi yaturutse kwa A-Nawas Ibun Sam'aan Al Answariy (Imana imwishimire) yavuze ko Intumwa y'Imana (Imana iyihe amahoro n'imigisha) yavuze iti: "Allah yatanze urugero rw'ubuyisilamu abugereranya nk'inzira igororotse ariko mu mpande zayo hari inkuta ebyiri, ziriho imiryango itandukanye ifunguye. No kuri buri muryango hariho amarido, no ku ntangiriro z'iyo nzira hari umuhamagazi uyobora abantu ababwira ati: Yemwe bantu! Nimukurikire inzira igororotse mwese uko mwakabaye kandi muramenye ntimukurikire utundi tuyira! Hari n'undi uhagaze mu nzira hejuru, ushatse gufungura ngo anyure muri umwe muri ya miryango akamubuza amubwira ati: Uritonde, ntuwufungure, kubera ko nuwufungura urahita uwinjiramo nturi bubashe kongera kugaruka. Iyo nzira ni ubuyisilamu, inkuta ebyiri ni amategeko ya Allah, indi miryango ifunguye ni ibyo Allah yaziririje, naho wa wundi uri mu ntangiriro y'inzira ayobora abantu ni igitabo cya Allah Qur'an, uri mu nzira hejuru abuza abantu kwinjira muri ya miryango ni umutimanama buri muyisilamu afite uba umugira inama yo kutishora mu biziririjwe."
