Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: I was in the house of Sayyidah Maymunah bint al-Harith (may Allah be pleased with her), and I placed water for ablution (wudu) for the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said: "Who placed this?" Sayyidah Maymunah (may Allah be pleased with her) said: Abdullah placed it. He (peace and blessings be upon him) said: "O Allah! Teach him interpretation (ta'wil), and grant him understanding of the religion."
