Al-An'am
According to Ibn 'Abbas, this entire Surah was revealed in Makkah at the same time. Hazrat Asma bint Yazid , the cousin of Hazrat Muaz Ibn Jabal , said that this Surah was revealed while the Prophet (peace and blessings of Allaah be upon him) was riding on a camel. Then I was holding the reins of her camel. Under the weight of the burden, the camel's condition had reached such a level that it seemed as if this understanding would break her bones. It is also clearly stated in the hadith that the Prophet (peace and blessings of Allaah be upon him) recorded this Surah on the night it was revealed.
