It is narrated from Dawud bin Abi Salih that one day Marwan came and found a man placing his face on the blessed grave (of the Prophet (peace and blessings be upon him)). Marwan seized the man by the neck and said: Do you know what you are doing? When the man turned towards Marwan, it was Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him). He said (in reply to Marwan): Yes (I know very well). I have come into the presence of the Messenger of Allah (peace and blessings be upon him); I have not come to a stone. I heard the Messenger of Allah (peace and blessings be upon him) saying: "Do not shed tears over the religion when those in charge of it are its worthy (righteous and deserving) people; rather, weep and lament over the religion when those who are not worthy of it become its guardians and custodians." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs did not record it.
