Sunan Ibn Majah, Book 37, Hadith 4431 (In-Book) ⓘ
It was narrated from Ibn ‘Abbas that the Prophet said: “We are the last of the nations, and the first to be brought to account. It will be said: ‘Where is the unlettered nation and its Prophet?’ So we are the last and the first.”
حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى، حَدَّثَنَا أَبُو سَلَمَةَ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ سَعِيدِ بْنِ إِيَاسٍ الْجُرَيْرِيِّ، عَنْ أَبِي نَضْرَةَ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ قَالَ نَحْنُ آخِرُ الأُمَمِ وَأَوَّلُ مَنْ يُحَاسَبُ يُقَالُ أَيْنَ الأُمَّةُ الأُمِّيَّةُ وَنَبِيُّهَا فَنَحْنُ الآخِرُونَ الأَوَّلُونَ " .
