Bukhari:V1B4N163 “The Prophet said, ‘Whoever cleans his private parts with stones should do it with an odd number of stones. And whoever wakes up should wash his hands before putting them in the water for ablution. Nobody knows where his hands were during sleep.’”
Bukhari:V1B4N174 “During the lifetime of Allah’s Apostle dogs used to urinate and pass through the mosque. Nevertheless they never used to sprinkle water on it.”
