The word عسر in the Quran

شَهْرُ رَمَضَانَ ٱلَّذِىٓ أُنزِلَ فِيهِ ٱلْقُرْءَانُ هُدًى لِّلنَّاسِ وَبَيِّنَٰتٍ مِّنَ ٱلْهُدَىٰ وَٱلْفُرْقَانِ فَمَن شَهِدَ مِنكُمُ ٱلشَّهْرَ فَلْيَصُمْهُ وَمَن كَانَ مَرِيضًا أَوْ عَلَىٰ سَفَرٍ فَعِدَّةٌ مِّنْ أَيَّامٍ أُخَرَ يُرِيدُ ٱللَّهُ بِكُمُ ٱلْيُسْرَ وَلَا يُرِيدُ بِكُمُ ٱلْعُسْرَ وَلِتُكْمِلُوا۟ ٱلْعِدَّةَ وَلِتُكَبِّرُوا۟ ٱللَّهَ عَلَىٰ مَا هَدَىٰكُمْ وَلَعَلَّكُمْ تَشْكُرُونَ ۝١٨٥

The month of Ramaḍān [is that] in which was revealed the Qur’ān, a guidance for the people and clear proofs of guidance and criterion. So whoever sights [the crescent of] the month, let him fast it; and whoever is ill or on a journey - then an equal number of other days. Allāh intends for you ease and does not intend for you hardship and [wants] for you to complete the period and to glorify Allāh for that [to] which He has guided you; and perhaps you will be grateful.

قَالَ لَا تُؤَاخِذْنِى بِمَا نَسِيتُ وَلَا تُرْهِقْنِى مِنْ أَمْرِى عُسْرًا ۝٧٣

[Moses] said, "Do not blame me for what I forgot and do not overwhelm me in my matter with difficulty."

مُّهْطِعِينَ إِلَى ٱلدَّاعِ يَقُولُ ٱلْكَٰفِرُونَ هَٰذَا يَوْمٌ عَسِرٌ ۝٨

Racing ahead toward the Caller. The disbelievers will say, "This is a difficult Day."

لِيُنفِقْ ذُو سَعَةٍ مِّن سَعَتِهِۦ وَمَن قُدِرَ عَلَيْهِ رِزْقُهُۥ فَلْيُنفِقْ مِمَّآ ءَاتَىٰهُ ٱللَّهُ لَا يُكَلِّفُ ٱللَّهُ نَفْسًا إِلَّا مَآ ءَاتَىٰهَا سَيَجْعَلُ ٱللَّهُ بَعْدَ عُسْرٍ يُسْرًا ۝٧

Let a man of wealth spend from his wealth, and he whose provision is restricted - let him spend from what Allāh has given him. Allāh does not charge a soul except [according to] what He has given it. Allāh will bring about, after hardship, ease [i.e., relief].

فَإِنَّ مَعَ ٱلْعُسْرِ يُسْرًا ۝٥

For indeed, with hardship [will be] ease [i.e., relief].

إِنَّ مَعَ ٱلْعُسْرِ يُسْرًا ۝٦

Indeed, with hardship [will be] ease.
