“Verily, with hardship comes ease.”

Indeed, with hardship will be ease.

One of the earliest surahs, revealed in Makkah while the Prophet (peace be upon him) was carrying the full weight of rejection. It opens by reminding him that his chest has already been opened and his burden already lifted, and only then makes this promise — twice, in consecutive verses. Ibn Kathir explains the grammar: "the hardship" is definite both times, so it is one hardship, while "ease" is indefinite, so it is more than one. He records that al-Hasan al-Basri related the Prophet came out one day smiling and saying, "One hardship will never overcome two eases."
