Mishkat al-Masabih #386

‘Abdallah b. al-Mughaffal on hearing his son say, “O God, I ask Thee for the white palace on the right of paradise,” said, “Sonny, ask God for paradise and seek refuge in Him from hell, for I heard God’s Messenger say, ‘There will be some among this people who will go over the score in ablution and supplication.” Ahmad, Abu Dawud and Ibn Majah transmitted it.
