Qur'ani iliteremshwa kwa sehemu kwa Mtume Muhammad ﷺ tangu mwanzo wa utume wake hadi muda mfupi kabla ya kifo chake. Hivyo, Qur'ani iliteremka mfululizo kwa kipindi cha miaka ishirini na mitatu.

The Qur’aan was revealed in sections to Prophet Muhammad (r) from the beginning of his prophethood until shortly before his death. Thus, the Qur’aan came down continuously over a period of twenty-three years.

Sehemu mbalimbali za Qur'ani kwa ujumla ziliteremshwa ili kutatua matatizo yaliyokuwepo miongoni mwa jamii za Waislamu, huko Makka na huko Madina. Kwa kuwa matatizo na mahitaji ya Makka yalikuwa tofauti na yale ya Madina, ufunuo wa Makka na wa Madina una sifa zake maalum.

The various sections of the Qur’aan were generally revealed to solve the problems which existed among the Muslim communities in both Makkah and Madeenah. Since the prob-lems and needs of Makkah were different from those of Madeenah, the revelations of Makkah and Madeenah have special characteristics of their own.

Ni muhimu sana kuelewa tofauti kati ya wahyu za Makkah na za Madinah ili Qur'ani yenyewe ieleweke vizuri. Kwa sababu ya umuhimu mkubwa wa Qur'ani katika Uislamu, wanazuoni wa Kiislamu tangu zama za Maswahaba wametumia muda mwingi na juhudi nyingi katika eneo hili la utafiti.

It is very important that the differences between the revelations of Makkah and Madeenah be clearly understood if the Qur’aan itself is to be clearly understood. Because of the great importance of the Qur’aan to Islaam, Islaamic scholars from the time of the sahaabah have devoted much time and effort in this area of study
