There will be people in this Ummah who transgress in purification and supplication

It is narrated from Sayyiduna Abdullah bin Mughaffal (may Allah be pleased with him) that he heard his son making this supplication: "O Allah! I ask You for the white palace on the right side of Paradise when I enter it." He said: "O my son! Ask Allah for Paradise and seek His refuge from the Fire, for I heard the Messenger of Allah (peace and blessings be upon him) say: 'Soon there will be people in this Ummah who will transgress the limits in purification (ablution) and in supplication.'"

Sayyiduna Abdullah bin al-Harith bin Jaz' al-Zubaydi (may Allah be pleased with him) narrates that he heard the Prophet (peace and blessings be upon him) say: "Woe (a threat of ruin) from the Fire for the heels and the soles of the feet!"
This hadith is sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record the mention of the soles of the feet in it.
