Answered by Ustadh Sufyan Qufi
I know that Shias believe that if there is cat hair on your prayer clothes, then your prayer is void. Is this true? (I am a Sunni)
In the name of Allah, Most Compassionate, Most Merciful,
I pray this finds you in the best of states.
No, the presence of cat hair in your clothes won’t invalidate your prayer.
The reason for this ruling is that as long as your body, clothing, and place of prayer are not affected by more than 5 grams of solid filth, then your prayer is valid. [Ibn ‘Abidin, Radd al-Muhtar]
If the hair is from a cat, then the hair’s head (the moist part only) is filthy. As for the rest of the hair, it is pure. This is a very small area that weighs far less than 5 grams. It is thus excused to pray while being affected by a low amount of cat hair.
The Messenger of Allah (Blessings and Peace be upon Him) has said regarding dead (non-ritually slaughtered) animals: “It is forbidden to eat it.” while allowing us to benefit from its skin by tanning it and using it as containers and so on. [Bukhari]
This indicates that the hair of an animal is pure. [Ibn ‘Abidin, Radd al-Muhtar]
And Allah knows best.
