Answered by Ustadh Sufyan Qufi
If fluid najasa is scattered over many places of the body and clothes, what affects the validity of the prayer total when all of it is gathered together or the amount of najasa in each location?
In the name of Allah, Most Compassionate, Most Merciful,
The total amount of filth is what is considered when determining whether or not the prayer is valid. [Shurunbulali, Nur al-Idah]
If one has been affected by several stains of blood, for example, then if the total surface of these stains exceeds a circle of 5 cm in diameter, then the prayer is invalid, even if each of these stains is smaller than this circle when considered individually. [ibid]
The reason for this ruling is that whether the filth is scattered over your clothes or gathered in one place, when the total amount is beyond the excused amount of filth, we have no choice but to accept that it is now obligatory to remove this filth in order to ensure the validity of the prayer.
Allah, Most High, says: “Purify your garments.” [Quran, 74:4], i.e., in the prayer. [Laknawi, Hashiya ‘Ala al-Hidaya]
And Allah knows best.
