Yahya related to me from Malik from Yahya ibn Said from Muhammad ibn Ibrahim ibn alHarith at-Taymi from Yahya ibn Abd ar-Rahman ibn Hatib that Umar ibn al-Khattab set out on one occasion with a party of riders, one of whom was Amr ibn al-As. They came to a watering place and Amr ibn al-As asked the man who owned it whether wild beasts drank from it. Umar ibn al-Khattab told the owner of the watering place not to answer, since the people drank after the wild beasts and the wild beasts drank after them.  

أَنَّ عُمَرَ بْنَ الْخَطَّابِ خَرَجَ فِي رَكْبٍ فِيهِمْ عَمْرُو بْنُ الْعَاصِ حَتَّى وَرَدُوا حَوْضًا فَقَالَ عَمْرُو بْنُ الْعَاصِ لِصَاحِبِ الْحَوْضِ يَا صَاحِبَ الْحَوْضِ هَلْ تَرِدُ حَوْضَكَ السِّبَاعُ فَقَالَ عُمَرُ بْنُ الْخَطَّابِ يَا صَاحِبَ الْحَوْضِ لاَ تُخْبِرْنَا فَإِنَّا نَرِدُ عَلَى السِّبَاعِ وَتَرِدُ عَلَيْنَا
