Ruling on offering Janazah Prayer after burying a deceased after `Asr Prayer

A: Whoever misses offering Janazah Prayer over the deceased, it is Mustahab (desirable) to offer Janazah Prayer for them over their grave. The grave should be in a middle position between them and the Qiblah (Ka`bah-direction faced in Prayer). It is permissible to offer it within the period of a month from their burial, according to the Hadith narrated by Abu Hurayrah (may Allah be pleased with him) who said: A black woman who used to sweep the Masjid (mosque) died. The Prophet (peace be upon him) inquired about her. The people told him that she had died. He (peace be upon him) said, 'Why did you not inform me?' (Part No. 7; Page No. 265) He (peace be upon him) then said, 'Lead me to her grave.' They led him to it and he (peace be upon him) prayed over her. (Agreed upon by Al-Bukhari and Muslim) It was also narrated by Sa`id ibn Al-Musayyib that Um Sa`d died while the Prophet (peace be upon him) was not there. When he (peace be upon him) came, he prayed over her, and a month had gone by since that (her death). (Related by Al-Tirmidhy; its narrators are Thiqah [trustworthy]) Imam Ahmad said: "The longest period during which it is permissible to offer Janazah Prayer is a month. There is nothing wrong in extending this period for one or two more days. Beyond this period, Janazah Prayer should not be offered over the deceased. Rather, one should supplicate Allah to have mercy on and forgive them."May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
