Sayyiduna Anas (may Allah be pleased with him) says: When the Prophet (peace and blessings be upon him) woke up at night, he would cleanse himself after relieving himself, then perform ablution and use the miswak. Then he (peace and blessings be upon him) would ask for perfume in the houses of his wives.
This narration was recorded by Imam al-Bazzar, and its narrators have been declared trustworthy.
