Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates: A man said, "O Messenger of Allah! Whenever I perform ablution, (blood) starts to flow." The Prophet Muhammad (peace be upon him) said, "When you have performed ablution, then even if it continues to flow from the top of your head to your feet, it is not obligatory for you to perform ablution again." Abdullah bin Malik Ramawi is weak; this narration is not authentic.
