Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The Noble Prophet (peace and blessings be upon him) said: "Whoever performs ablution and mentions the name of Allah at the beginning, his entire body becomes purified." The Noble Prophet (peace and blessings be upon him) also said: "Whoever performs ablution and does not mention the name of Allah at the beginning, only his specific limbs become purified."
