סימן קצז סעיף י

אֲפִלּוּ יָצָא מִמֶּנוּ דָם, אֶלָּא שֶׁכְּבָר פָּסַק, וּפָשְׁטוּ אֶת בְּגָדָיו, וְחַי אַחֲרֵי זֶה אֵיזֶה יָמִים, וְאַחַר כָּךְ מֵת, מְטַהֲרִין אוֹתוֹ, וְעוֹשִׂין לוֹ תַכְרִיכִין. וְאַף עַל פִּי שֶׁהוּא מְלֻכְלָךְ מִדָם שֶׁיָצָא מִמֶּנּוּ, אֲפִלּוּ הָכִי מְטַהֲרִין אוֹתוֹ, כִּי אֵין לָחוּשׁ לְדָם שֶׁיָצָא מִמֶּנּוּ בַחַיִּים, אֶלָּא לְדָם שֶׁיָצָא מִמֶּנוּ בִשְׁעַת מִיתָה, חָיְשֵׁינָן שֶׁמָּא הוּא דַם הַנֶּפֶשׁ, אוֹ שֶׁמָּא נִתְעָרֵב בּוֹ דַּם הַנָּפֶשׁ.

Even if blood issued from his body but it stopped, and his clothes were removed, after which he lived for a few days and died, his body must be ritually cleansed and dressed in shrouds. Even though his body is stained from the blood which issued from him, he still must be cleansed, because we are not concerned [about washing off the blood] that issued when he was alive. We are concerned only about the blood which issued from him while he was dying because it may have been his lifeblood, or that his lifeblood was mixed with it.

תנא דבי אליהו כל השונה הלכות בכל יום מובטח לו שהוא בן העולם הבא שנאמר הליכות עולם לו אל תקרי הליכות אלא הלכות (נדה ע"ג.)
