✅Answer: Consider the following narrations:

📚 Al-Tahdhib, vol.1, p.427

1 عَنْ عَمْرِو بْنِ شِمْرٍ عَنْ جَابِرٍ عَنْ أَبِي جَعْفَرٍ قَالَ: قَالَ رَسُولُ اللَّه يَا مَعْشَرَ النَّاسِ لَا أَلْقَيَنَ [أُلْفِیَنَ] رَجُلًا مَاتَ لَهُ مَيِّتٌ لَيْلًا فَانْتَظَرَ بِهِ الصُّبْحَ وَ لَا رَجُلًا مَاتَ لَهُ مَيِّتٌ نَهَاراً فَانْتَظَرَ بِهِ اللَّيْلَ لَا تَنْتَظِرُوا بِمَوْتَاكُمْ طُلُوعَ الشَّمْسِ وَ لَا غُرُوبَهَا عَجِّلُوا بِهِمْ إِلَى مَضَاجِعِهِمْ يَرْحَمُكُمُ اللَّهُ قَالَ النَّاسُ وَ أَنْتَ يَا رَسُولَ اللَّهِ يَرْحَمُكَ اللَّهُ.

📚 Al-Kafi, vol.3, p.137

Imam Baqir (peace be upon him) said: The Messenger of Allah (peace be upon him and his family) said: 'O people, never delay the burial of a deceased person until morning if he died at night, and never delay until night if he died during the day! Do not wait for sunrise or sunset for your deceased. Hasten to take them to their resting place, may Allah have mercy on you!'

People said: 'And may Allah have mercy on you as well, O Messenger of Allah!'

📚 Al-Tahdhib, vol.3, p.320

2 عَنْ عَمْرِو بْنِ شِمْرٍ عَنْ جَابِرٍ قَالَ: قُلْتُ لِأَبِي جَعْفَرٍ إِذَا حَضَرَتِ الصَّلَاةُ عَلَى الْجِنَازَةِ فِي وَقْتِ مَكْتُوبَةٍ فَبِأَيِّهِمَا أَبْدَأُ فَقَالَ عَجِّلِ الْمَيِّتَ إِلَى قَبْرِهِ إِلَّا أَنْ تَخَافَ أَنْ يَفُوتَ وَقْتُ الْفَرِيضَةِ وَ لَا تَنْتَظِرْ بِالصَّلَاةِ عَلَى الْجِنَازَةِ طُلُوعَ الشَّمْسِ وَ لَا غُرُوبَهَا.

Jabir asked Imam Baqir (peace be upon him): If the funeral prayer coincides with the time of a fard prayer, which should we prioritize? The Imam said: 'Hasten to bury the deceased unless you fear missing the fard prayer.' Do not wait for sunrise or sunset for the funeral prayer.

📚 Al-Kafi, vol.3, p.138

Imam Sadiq (peace be upon him) said: The Messenger of Allah (peace be upon him and his family) said: 'When a person dies early in the day, do not delay their burial until midday nap; bury them in their grave promptly.'

3 عَنْ هَارُونَ بْنِ الْجَهْمِ عَنِ السَّكُونِيِّ عَنْ أَبِي عَبْدِ اللَّه قَالَ: قَالَ رَسُولُ اللَّهِ إِذَا مَاتَ الْمَيِّتُ أَوَّلَ النَّهَارِ فَلَا يَقِيلُ إِلَّا فِي قَبْرِهِ.

📚 Al-Tahdhib, vol.1, p.433

Imam Baqir (peace be upon him) said: 'When a person dies, begin preparing them immediately and hasten the process.'

4 عَنْ عِيصٍ عَنْ أَبِي عَبْدِ اللَّهِ عَنْ أَبِيه قَالَ: إِذَا مَاتَ الْمَيِّتُ فَخُذْ فِي جَهَازِهِ وَ عَجِّلْهُ

📚 Al-Faqih, vol.1, p.140

Sheikh Saduq says: The Messenger of Allah (peace be upon him and his family) said: 'Honoring the deceased is by hastening their preparation and burial.'

5 مُحَمَّدُ بْنُ عَلِيِّ بْنِ الْحُسَيْنِ قَالَ: قَالَ رَسُولُ اللَّهِ كَرَامَةُ الْمَيِّتِ تَعْجِيلُهُ.

✅As these narrations indicate, it is emphasized to hasten the preparation and burial of the deceased. Delaying burial for relatives arriving from other cities or countries, or for a specific day such as Friday, is not a valid excuse. Burial should not wait until night or morning; after death, one must immediately engage in washing, shrouding, praying over, and burying the deceased.

✅Exceptions are noted in the following narration:

📚 Al-Kafi, vol.3, p.210

Imam Sadiq (peace be upon him) said: There are five cases where burial may be delayed until changes occur in the body confirming death: a drowned person, a lightning-struck person, a person who died with abdominal issues (bloated), a person buried under a collapsed building, and a person affected by smoke.

✅Such cases may be delayed up to three days unless the body changes beforehand confirming death. According to 📚 Al-Kafi, vol.3, p.209, sometimes it may appear that the person is dead while they are not yet dead.

6 عَنْ إِسْمَاعِيلَ بْنِ عَبْدِ الْخَالِقِ ابْنِ أَخِي شِهَابِ بْنِ عَبْدِ رَبِّهِ قَالَ: قَالَ أَبُو عَبْدِ اللَّه خَمْسٌ يُنْتَظَرُ بِهِمْ إِلَّا أَنْ يَتَغَيَّرُوا الْغَرِيقُ وَ الْمَصْعُوقُ وَ الْمَبْطُونُ وَ الْمَهْدُومُ وَ الْمُدَخَّنُ
