3. Ali ibn Ibrahim has narrated from his father, from Hammad, from Hariz, from Muhammad ibn Muslim who has said the following: “I once said to him (the Imam), ‘I may find blood on my clothes when I am performing Salah (prayer).’ He (the Imam) said, ‘If you find blood and you have other clothes on you, you must remove it and complete your Salah (prayer). However, if you do not have other clothes on you besides that one, you must complete your Salah (prayer). You do not have to perform that Salah (prayer) again if the area covered by that blood is not more than the size of a dirham, and an area of smaller size does not matter, regardless if you have seen it before or not. If you have seen it before and it is bigger than the size of a dirham, but you have missed to wash it and have performed with it many Salah (prayer), you must perform again the Salah (prayers) you have performed with it.’”

6.

7. Ali ibn Ibrahim has narrated from Ahmad ibn abu ‘Abd Allah from his father in a marfu‘ manner who has said the following: “Abu ‘Abd Allah (a.s.), has said that your blood to you is less unclean than other people’s blood. If you find like sprinkles of your blood on you, it is not harmful; but if it is other people’s blood, regardless of its being of a small or large quantity, you must wash it clean.’”

Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Sinan from ibn Muskan from al-Halabiy who has said the following: “I once asked abu ‘Abd Allah (a.s.), about the blood of fleas on one’s clothes - if it is harmful to his Salah (prayer). He (the Imam) said, ‘It is not harmful even if they are many. So also is the case with similar things, like sprinkled nostril blood which one does not have to wash.’” “It is narrated also that things cannot be washed with saliva except blood (inside one’s mouth).”’
