The Apostle of Allah (ﷺ) said: When anyone amongst you wakes up from sleep, he should wash his hands three times before putting it in the utensil, for he does not know where his hand was during the night.
This hadith has been transmitted through other chains of transmitters on the authority of Abu Huraira in which it is reported that the Messenger of Allah (ﷺ) made a mention of washing the hand, and did not instruct to wash it three times. But the hadith narrated from Jabir and Ibn Musayyab. Abu Salama, and Abdullah b. Shaqiq, Abu Salih, Abla Razin, there is a mention of" three times".
When a dog licks a utensil belonging to any one of you, (the thing contained in it) should be thrown away and then (the utensil) should be washed seven times.
The Messenger of Allah (ﷺ) said: The purification of the utensil belonging to any one of you, after it is licked by a dog, lies in washing it seven times, using sand for the first time.
Of the a hadith narrated by Abu Huraira from Muhammad, the Messenger of Allah (ﷺ), one is this: The Messenger of Allah (ﷺ) said: The purification of the utensil belonging to one amongst you, after it is licked by a dog, lies in washing it seven times.
The Messenger of Allah (ﷺ) ordered killing of the dogs, and then said: What about them, i. e. about other dogs? and then granted concession (to keep) the dog for hunting and the dog for (the security) of the herd, and said: When the dog licks the utensil, wash it seven times, and rub it with earth the eighth time.
" He (the Holy Prophet) gave concession in the case of the dog for looking after the herd, for hunting and for watching the cultivated land," and there is no mention of this addition (i. e. concession in case of watching the cultivated lands) except in the hadith transmitted by Yahya.
