Answered by Shaykh Faraz Rabbani
How does one clean najasa (both visible and invisible) off carpets? If it is in a corner area where flowing water can run over it I presume this is the best way. But what about if it is in the middle of the carpet? I was speaking to one scholar here who said that the spot must have water applied to it and then let it dry 3 times over. This seems like a big hardship. It could take at least 3 days to clean it using this method
Walaikum assalam,
What some books mean by ‘dried,’ as other texts (such as Ibn Abidin’s Hashiya) explain is, ‘no longer dripping.’
Removing filth (najasa) from a carpet is not very difficult, inshaAllah:
1. It is best to minimize the filth (najasa) by wiping away its traces, using a moist cloth, for example.
2. Determine the affected area. Then, pour water over that area. Soak up the water with a cloth, until the carpet is no longer dripping wet. Do this three times, in total. After this, the carpet has been rendered pure (tahir), as long as no trace of the filth remains. [This is mentioned in Maraqi al-Falah, Radd al-Muhtar, and elsewhere]
Wassalam,
