Re: Halal food and dishes
& Peace,
Scholars share different opinions. Some say the pan or any utensil should be washed seven times. Some other says it should be rubbed with sand six times and one time with water. Many others says eight time. I unable to find any direct narration regarding this. However what I know I’ll share it with you as per my best understanding but I suggest you to consult with qualified Aalam or Scholar. How to wash? plz refer the hadiths below:
In Sahih Muslim, it is narrated that if dog licks any utensil than it should be washed seven times. Many scholars from the context of these hadiths said if ‘haraam’ things i.e. pork etc., is cooked in that pan or served in any utensil than it should be washed seven times.
**Book ‘The Book of Purification (Kitab Al-Taharah)’ of Sahih Muslim Hadith No. 0546, 0549, 0551.
**
Abu Huraira reported the Messenger of Allah 
to have said: 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.
Abu Huraira reported: The Messenger of Allah 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.
Ibn Mughaffal reported: The Messenger of Allah 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.
Almighty Allah knows best.
