Q: Is it right that
the Glorious Qur'an was revealed in seven Ahruf (modes of recitation)
Yes, it is right that the Glorious Qur'an was revealed in seven Ahruf. (Part No. 3; Page No. 63) It was authentically reported on the authority of
`Umar ibn Al-Khattab (may Allah be pleased with him) that the Prophet (peace be upon him) said:
Verily, this Qur'an has been revealed in seven Ahruf, so recite it in the way that is easiest for you.
Al-Tirmidhy) There are many Hadiths related in this regard through different chains of transmissions and with different wording. We refer you to the first part of Tafsir of
Ibn Jarir Al-Tabary and the books on Qira'at (recitation styles) to know what is exactly meant by seven Ahruf and the wisdom behind revealing the Qur'an in them.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
