Al-Inshirāḥ's subject matter seems a continuation of the reassurance and encouragement given in the preceding chapter and so closely resembles it that both these Surah seem to have been revealed in about the same period under similar conditions.
[2] Regarding the timing and contextual background of the revelation (asbāb al-nuzūl), it is an earlier "Meccan surah", which means it is believed to have been revealed in Mecca, instead of later in Medina.
The first is the blessing of Sharh Sadr (opening up of the chest), the second of removing from you the heavy burden that was weighing down your back before the call, and the third of exalting your renown the like of which has never been granted to any man before."
The Surah also repeats the phrase "Surely with hardship comes ease", setting a precedent that appears throughout the Quran that any single difficulty faced by Muhammad or his followers would be rewarded twice over (or more).
[4] In conclusion, Muhammad has been instructed, to say, "You can develop the power to bear and resist the hardships of the initial stage only by one means, and it is this: 'When you are free from your occupations, you should devote yourself to the labor and toil of worship, and turn all your attention exclusively to your Lord'."
