And many a township did I give respite while it was given to wrongdoing. Then I seized it (with punishment). And to Me is the (final) return (of all).
Ibn Abi Hatim recorded from Abu Hurayrah that the Messenger of Allah said:
يَدْخُلُ فُقَرَاءُ الْمُسْلِمِينَ الْجَنَّةَ قَبْلَ الاَْغْنِيَاءِ بِنِصْفِ يَوْمٍ خَمْسِمِايَةِ عَام
The poor among the Muslims will enter Paradise half a day before the rich -- five hundred years.
This was recorded by At-Tirmidhi and An-Nasa'i from the Hadith of Ath-Thawri from Muhammad bin `Amr.
At-Tirmidhi said, "Hasan Sahih."
Abu Dawud recorded at the end of Book of Al-Malahim in his Sunan from Sa`d bin Abi Waqqas that the Prophet said:
إِنِّي لاََرْجُو أَنْ لاَ تَعْجِزَ أُمَّتِي عِنْدَ رَبِّهَا أَنْ يُوَخِّرَهُمْ نِصْفَ يَوْم
I hope that it will not be too much for my Ummah if Allah delays them for half a day.
It was said to Sa`d, "What does half a day mean?"
He said, "Five hundred years."
