It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) passed by Sayyiduna Sa’d (may Allah be pleased with him) while he was performing ablution. The Prophet (peace and blessings be upon him) said:“Sa’d! What is this extravagance?”He said:“Is there extravagance even in ablution?”The Prophet (peace and blessings be upon him) replied:“Yes, even if you are at a flowing river.”
