Hadith: Everything is decreed, even incapacity and capacity, or capacity and incapacity

عَنْ طَاوُسٍ أَنَّهُ قَالَ: أَدْرَكْتُ نَاسًا مِنْ أَصْحَابِ رَسُولِ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ، يَقُولُونَ كُلُّ شَيْءٍ بِقَدَرٍ، قَالَ: وَسَمِعْتُ عَبْدَ اللهِ بْنَ عُمَرَ رضي الله عنهما يَقُولُ: قَالَ رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ:
«كُلُّ شَيْءٍ بِقَدَرٍ، حَتَّى الْعَجْزِ وَالْكَيْسِ، أَوِ الْكَيْسِ وَالْعَجْزِ».
[صحيح] - [رواه مسلم]

Tāwūs reported: I found some of the Prophet's Companions say: "Everything is decreed." I heard ‘Abdullah ibn ‘Umar say: The Messenger of Allah (may Allah’s peace and blessings be upon him) said:
"Everything is decreed, even incapacity and capacity, or capacity and incapacity."
Sahih/Authentic. - [Muslim]

Explanation

The Prophet (may Allah's peace and blessings be upon him) pointed out that everything is decreed, even incapacity, which is failure to do what should be done - in matters of this world and the Hereafter - and procrastinating and delaying it beyond its due time; and even capacity, which is vigor and proficiency in matters of worldly life and the Hereafter; and that Allah Almighty had predestined capacity and incapacity, and everything that happens in the universe had already been known and willed by Allah.
