It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever's hand touches his private part with no barrier between them, ablution for prayer is obligatory upon him."
(b) Yazid bin Abd al-Malik has been criticized. Imam Ahmad bin Hanbal (may Allah have mercy on him) was asked about Yazid bin Abd al-Malik al-Nawfali, and he said: He is a shaykh of the people of Madinah; there is no harm in him.
(c) The Shaykh said: This has a basis (asl) from Sayyiduna Abu Hurayrah (may Allah be pleased with him).
