Why does Allah mention that humans were created in hardship (fi kabad)?
Salam Aleikom,
Why does Allah say that human was created in haradship (fi Kabad)? Are tasks easy or hard for Allah to do?
Also, I am looking to find a good book on Tafsir of Quran. Any suggestions please?
Kabad in Qur'an 90:4, usually understood to mean "difficulty", is generally taken to refer to the difficulties of physical life that are experienced while living on earth that are the result of the nature of our bodily existence, our need to work and obtain food, and so forth. (Sometimes, it is also understood to refer to difficulties in the afterlife) So it is not referring to Allah experiencing hardship.
Books of tafsir: A good general book is The Study Quran, edited by S. H. Nasr, which contains a summary of views from many exegetes.
Many people benefit from Tasfir al-Mizan; some of it is available in English online and some other parts can be purchased in print.
If you have an interest in Twelver Shi'i narration-based tafsir, Tafsir al-Ayyashi can be purchased in English, and, God willing, al-Asfa fi Tafsir al-Quran by Fayd Kashani will also be printed in English within this year.
If you have a preference for conventional Sunni tafsir, there are many choices in English.
Best wishes!
