عَنْ سَعْدِ بْنِ أَبِي وَقَّاصٍ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّهُ كَانَ يَقُولُ ”لَا تَعْجِزُ أُمَّتِي عِنْدَ رَبِّي أَنْ يُؤَخِّرَهَا نِصْفَ يَوْمٍ“ وَسَأَلْتُ رَاشِدًا هَلْ بَلَغَكَ مَاذَا النِّصْفُ يَوْمٍ قَالَ خَمْسُ مِائَةِ سَنَةٍ
It is narrated from Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him), the Noble Prophet (peace and blessings be upon him) said: My Ummah will not be incapable before my Lord that He would keep them held in account for half a day. Abu Bakr says: I said to Rashid, “Have you received any information about how long half a day is?” He said: Five hundred years.
