Is this a hadith or an athar, and what is its degree of authenticity: (Sweeping the mosques is the mahr for the houris)?

The questioner : The Shaykh (may Allah preserve him) — the hadith: Is this a hadith or an athar, and what is its degree of authenticity?

The Shaykh : It is narrated as a hadith, but its chain of narration is not authentic. However, there is no doubt that sweeping the mosques, cleaning them, and caring for their fragrance and incense is a known sunnah (recommended practice). The story of that old woman who used to sweep the mosque of the Prophet (peace and blessings be upon him) "Then, whenever the Messenger of Allah (peace and blessings be upon him) entered the mosque, he would see this woman getting up and taking care of picking up the trash from the mosque. Then the Messenger of Allah (peace and blessings be upon him) stopped seeing her, so he asked about her. It was said to him (peace and blessings be upon him): She has died and they have buried her. He said:

Why did you not notify me?

أفلا آذنتموني

meaning: to pray over her. They excused themselves to him by saying that she died while he (peace and blessings be upon him) was sleeping, so they did not want to wake him from his sleep. Then he (peace and blessings be upon him) said:

Show me her grave, so he went with them and prayed over her while she was in her grave

دلوني على قبرها، فذهب معهم وصلى عليها وهي في قبرها

". This hadith alone is sufficient for us instead of the like of the hadith being asked about. This is an authentic hadith, and that one is a weak hadith, so it is not authentic. Yes.
