Pig related impurity

[new]

Assalamu Alaykum,

I had a question regarding tanned pig skin and its impurity. I know there is a difference of opinion regarding the purity of tanned pig leather, but this is not what I am enquiring about.

Often many shoes have pig skin linings and feet/socks become moist/sweaty with wear. I read a fatwa once (I think by sheikh othaimeen) explaining that touching an impure substance/surface with a wet hand for eg transfers the najasah.

Does this mean that when we step on carpet or floors etc with such damp socks (they are not WET just moist) the carpet becomes najis? Is such an amount of najasah negligible and overlooked?

My delimmah at the moment is that I have worn some shoes with this lining several times and then walked on the carpet with the socks.. Does this mean I can no longer pray on such a surface? or when I walk on the carpet again with wet feet (for eg after wudu) my feet become najis?

How do we determine which parts of the ground need purification (if that is in fact needed) if we do not know what the characteristics of this impurity is (for eg with urine there is smell/colour etc)

[Aslam AbuIsmaeel]

Wa alaikumus-salaam wa rahmatullah

A Najis substance, of course, is one that is regarded in the Shari'ah to be unclean and impure enough to prevent prayer and the like while it is on one's body, clothes or praying surface.

For a ground or clothes to become impure and be regarded as such, there needs to be some body substance of the Najis material on/in it.

So, some urine in clothes, faeces, menstrual blood, etc in clothes or on ground.

If none of this substance is found on the ground/clothes/body by visual inspection (or by touch) then it'd be regarded as pure.  If only some colour shading of Najis substance remains such that it does not go even after washing, then it is not a problem.  But if it can be then it must be washed away.  Likewise with the smell.

That is the general priniciple.

With regards to tanned pig skin lining on shoes, I am assuming that it is unlikely for its body substance to be transfered into the socks and further from it to the carpets.  The most may be some smell and perhaps some scattered particles but no solid body substance that is intact.  Unless otherwise, I'd assume that there is no Najasah transferred to the socks and especially to the carpet from the socks.  This is particularly the case with one that is tanned as opposed to untanned skin which may leave its tiny pieces here and there. 

As for touching impure substances, if one touched something such as urine or menstrual blood, they are liquid, so merely touching them with a wet hand is likely to have both mixing and thus hand becomes Najis.  If the hand was moist enough for such a Najasah's body substance to flow onto it, then the case is similar but provided it flows and transfers on.  Otherwise the hand remains pure.

Assalamu Alaykum,

I have read on islamqa regarding the impurity of dogs and was a bit confused regarding one point.

It seems that there is a difference of opinion regarding the purity of the dog itself (its body etc)... but the opinion of Shiekh Ibn Uthaimeen (along with other scholars) was that if one touches a dog with wet hands, then the hand becomes najiis.

Now, i dont have a dog myself.. but here in australia many people walk there dogs in the street etc.. sometimes in the rain, or the dog's feet are wet because of sweat etc.. This would mean that some spots on the ground become najiis? Would this also mean that when it rains, (since the water spreads all over), all the foot paths etc would become najjis? or do we assume that the water remains pure and hence the ground is also pure?

I would like to know if this mode of thinking is correct as I know the basic priniciple is things are pure unless proven otherwise.. how do I reconcile this with the opinion of some scholars (such as Sh ibn othaimeen) regarding transfer of naajassah when wet especially here in australia with the abundance of dogs and rain.

May Allah reward you with good
