It is narrated from Sayyiduna Abdullah bin Mughaffal (may Allah be pleased with him) that he heard his son supplicating: "O Allah, I ask You for the white palace on the right side of Paradise." He said: "(My son,) I heard the Messenger of Allah (peace and blessings be upon him) say: 'There will soon be people in this Ummah who will transgress the limits in supplication and in purification (ablution and the like).'" This hadith is sahih al-isnad (authentic in its chain), but the two Shaykhs did not record it.
