Those who permitted it and did not consider it to require ablution

Yahya bin Sa'id said: Once Sa'id bin al-Musayyib put his finger into his nose and some blood came out. Sa'id wiped it away and prayed without performing ablution.

Mujahid said: Sayyiduna Abu Hurayrah (may Allah be pleased with him) saw no harm in one or two drops of blood coming out during prayer (that is, he did not hold that they break the ablution).

Abu Qilabah did not hold that ablution is broken by a crack (in the skin) from which blood comes out.

Burd said: In the view of Makhul, if so little blood comes out of a man's nose that it can be wiped away with a finger, the ablution is not broken; but if it flows or drips, the ablution is broken.

Bakr said: I saw Sayyiduna Ibn Umar (may Allah be pleased with them both) squeeze a pimple on his face, and some blood came out. He wiped it away with his fingers and prayed without performing ablution.

Tawus did not hold that ablution is required even from flowing blood. In his view, simply washing off the blood is sufficient.

Al-Ala said: I asked Sa'id bin Jubayr: "If, after performing ablution, I take hold of the bucket to draw water, and the rope cuts my hand and blood comes out, what should I do?" He said: "Wash off that blood; there is no need to repeat the ablution."

Maymun bin Mihran said: Someone who saw Sayyiduna Abu Hurayrah (may Allah be pleased with him) informed us that he would put his finger into his nose, and if blood came out, he would wipe it off and then pray.

Abu al-Zubayr said: Sayyiduna Jabir (may Allah be pleased with him) would put his finger into his nose, and if blood came out, he would wipe it on the ground or on dust and then pray.

Abu Khaldah said: I saw Abu Sawwar squeeze a boil and then pray without performing ablution.
