At the Grave of the Prophet (s.a.w.)

‎ بِسۡمِ ٱللهِ ٱلرَّحۡمَـٰنِ ٱلرَّحِيمِ

Sayyidina Dawud ibn Swalih at-Tammar (r.a.) said, “One day, Marwan came, and he saw that a man was lying down with his mouth turned close to the Prophet’s (s.a.w.) grave.  Then he said to him, ‘Do you know what you are doing?’  When he moved towards him, he saw that it was Abu Ayyub al-Answari. 

He said, ‘Yes.  I have come to the Messenger of Allah (s.a.w.), and not to a stone.  I have heard it from the Messenger of Allah (s.a.w.) not to cry over religion, when its guardian is competent, but shed tears over religion, when its guardian is incompetent.’” 

In al-Mustadrak asw-Swahihayn, Imam Abu ‘Abdullah Muhammad ibn ‘Abdullah al-Hakim an-Nishaburi (r.a.) declared it swahih.  Imam Shams ad-Din Abu ‘Abdullah Muhammad ibn Ahmad adz-Dzahabi (r.a.) agreed with him.  Imam Ahmad ibn Muhammad ibn Hanbal (r.a.) recorded it, with a swahih chain of transmission, in his Musnad.
