The Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, narrated to me from Ahmad ibn Muhammad, from his father, from al-Husayn ibn al-Hasan ibn Aban, from al-Husayn ibn Sa'id, from Ibn Sinan, from Abu Basir, from Abu Abdullah عليه السلام, who said: I asked Imam عليه السلام about a person in a state of Janabah (major ritual impurity) who places a jug or bowl and dips their finger into it. Imam عليه السلام said: "If their hand is impure, pour out the water. But if no impurity has touched their hand, they may use it to perform Ghusl (ritual purification)." This is in accordance with Allah’s سبحانه وتعالى statement: "He has not placed upon you in the religion any difficulty" (Surah Al-Hajj 22:78).
