Garchi islomiy e'tiqod Allohga, Uning farishtalariga, Uning kitoblariga, Uning elchilariga, Qiyomat kuniga hamda qadar, ya'ni Allohdan kelgan yaxshi va yomon taqdirga iymon keltirishdan iborat bo'lsa-da, bu boshqa narsalarni e'tiqoddan chiqarib tashlash degani emas. Balki bu e'tiqodning asosini tashkil etishini anglatadi, shuningdek, payg'ambarlarning gunohsizligi kabi aqidaga oid boshqa fikrlar ham mavjud bo'lib, ular payg'ambarlarga iymon keltirish doirasiga kiradi. Payg'ambarlarning gunohsizligining dalili matnli dalil emas, balki aqliy dalildir, chunki biror payg'ambarning nubuvati va unga yuborilgan elchining risolati ko'zga ko'rinadigan mo''jiza bilan isbotlanadi, bu esa aqlan tasdiqlangan haqiqatdir.

Although the Islamic belief consists of belief in Allah , His Angels, His Books, His Messengers, the Day of Judgement and al-Qada wal-Qadar, both good and bad from Allah , it does not mean to exclude anything else from the belief. Rather, it means that this forms the basis of belief and there are other thoughts which relate to the ‘aqīdah (creed), such as the infallibility of the Prophets which also come under the belief in the prophets. The evidence of the infallibility of the Prophets is a rational evidence and not a textual evidence because the proof of the prophethood of a Prophet and the message of the messenger to whom he has been sent is rational, established by a perceptible miracle.
