A man putting his hand into a vessel while in a state of janabah

Sayyiduna Ibn Umar (may Allah be pleased with them both) said: If a man takes water from a vessel while in a state of janabah, the remaining water becomes impure. And the angels do not enter a house in which there is urine.

Al-Hasan (concerning a junub person who puts his hand into the vessel before washing it, or a person who gets up from sleep and puts his hand into the vessel before washing it) said: If he wishes, he may perform ablution with it, and if he wishes, he may pour it away.

Sa'id bin al-Musayyib said: There is no harm if a junub person puts his hand into the vessel before washing it.

Aishah bint Sa'd said: Sayyiduna Sa'd (may Allah be pleased with him) would order his slave-girl to bring water. She would draw it from the jar and bring the water for ablution, and she would put her hand into it. Sayyiduna Sa'd would be told that she was menstruating, and he would say: "Her menstruation is not in her hand."

Amir (al-Sha'bi) said that the Companions of Muhammad (peace and blessings be upon him) used to put their hands into the vessel while in a state of major ritual impurity (janabah), and the women while menstruating, before washing them, and they did not see any harm in that.
