How Should I Clean My Washing?

Shafi'i Fiqh

Answered by Shaykh Irshaad Sedick


What distinguishes the cleaning process between light filth and medium filth? It appears that light filth, despite being less significant, is easier to purify than moderately impure virtual filth.


In the Name of Allah, the Most Merciful and Compassionate.

Unless you are confident that najasa (filth as described by Sacred Law) came into contact with the clothes in your laundry, they are assumed clean (tahir). This means that while there may be dust, sand, and usual dirt on the clothing, they are not necessarily contaminated with najasa. In that case, any form of washing (including machine washing) will not be a problem and is permissible.

When you are confident that the clothing items were contaminated with najasa, the lighter view considers machine washing sufficient, and Allah knows best. Please visit our detailed response here, as well as this related answer. It is essential to note that indiscernible filth is also excused, as explained here.

The Default State is Purity

Two well-known principles in Sacred Law state: “The default status is everything is ritually pure (al-asl al-taharatu),” and “Certainty is not removed by doubt.” [Suyuti, al-Ashba wa al-Naza’ir]

The laws above entail that everything is pure unless one becomes sure that a particular item has become impure because one saw it come into contact with actual filth (najasa). And as long as you are not sure that it has become ritually impure (najis), it is to be considered pure, and you can apply all the rules of purity to it without any hesitation or doubt.

The Difference Between Light and Medium Filth

The question concerns the difference between light and medium filth.

Impurities are of Three Types:

  • Mughallaza (heavy).
  • Mukhaffafa (light).
  • Mutawassita (moderate/medium).

Heavy impurity is from a dog, pig, or their offspring.

Light impurity is the urine of a baby (boy), which only feeds on milk57 and is not yet two years of age.

All other remaining impurities are moderate impurities.

How to Clean Impurities

Heavy impurity becomes pure by removing it and then washing it seven times, one of which should be with earth.

Light impurity will be purified by removing the actual impurity and sprinkling adequate water upon it (the amount of water sprinkled should be greater than the amount of urine).

Moderate impurity is of two kinds: (1) that which has a substance and (2) that without a substance.

  1. That which has a substance is that which has a color, smell, and taste. It is necessary to remove its color, smell, and taste. (It is obligatory to remove all of its taste, even if it is difficult, and to remove both color and smell if not difficult. If any of the smell or color alone is difficult to remove, then the fact that one of these two remains does not affect the purity. However, if both the color and smell remain in a spot, it is not considered pure.)
  2. The one which has no substance is the one that does not have a color, smell and taste. It is sufficient that water flows over it. (If the effects of sun, fire, or wind remove the traces of the impurity, the affected item is still impure until water has been poured over it.)

I pray this is of benefit and that Allah guides us all.
