Surah az-Zukhruf (Ornaments) 43 : 34

Its period of revelation also could not be determined from any authentic tradition, but the internal evidence of the subject matter shows that this Surah too was sent down in the same period in which Surah 43: az-Zukhruf (Ornaments) and a few other earlier Surahs had been revealed. However, this Surah was sent down somewhat later. Its historical background is this: When the disbelievers of Makkah became more and more antagonistic in their attitude and conduct, the Prophet prayed: O God, help me with a famine like the famine of Joseph. He thought that when the people would be afflicted with a calamity, they would remember God, their hearts would soften and they would accept the admonition. God granted his prayer, and the whole land was overtaken by such a terrible famine that the people were sorely distressed. At last, some of the Quraysh chiefs among whom Abdullah bin Masud has particularly mentioned the name of Abu Sufyan came to the Prophet and requested him to pray to God to deliver his people from the calamity. On this occasion God sent down this Surah.
