The Prophet (blessings and peace of Allah be upon him) was as his Lord described him in the Qur’an: {There has certainly come to you a Messenger from among yourselves. Grievous to him is what you suffer; [he is] concerned over you and to the believers is kind and merciful} [al-Tawbah 9:128]. His offering the funeral prayer for the deceased was a mercy to him, and a light with which Allah would illuminate the grave of the deceased. In this hadith, Abu Hurayrah (may Allah be pleased with him) narrates that the Prophet (blessings and peace of Allah be upon him) asked about a black man or woman who used to clean and sweep the mosque, and they told him that she had died. So he said to his companions: “Why did you not tell me” and inform me that she had died? According to a report in al-Sahihayn, they thought little of the deceased and did not pay much attention to him. According to a report narrated by al-Nasa’i from Abu Umamah ibn Sahl ibn Hunayf (may Allah be pleased with him), they said: We did not want to wake you up at night. Then the Prophet (blessings and peace of Allah be upon him) asked about his or her grave, and he offered the funeral prayer for the deceased at the graveside, after the burial had taken place. This hadith highlights the virtue of cleaning the mosque, and of asking about a servant or friend when you do not see him for a while. It indicates that one may reciprocate by offering supplication, and that it is encouraged to attend the funerals of good people. It indicates that it is permissible to offer the funeral prayer at the grave of a deceased person in the same city, for one who did not attend his funeral, and that it is prescribed to announce deaths..
