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».
