Sahih al-Bukhari, Hadith 4310 ⓘ
(In an other narration) Ibn `Umar said: "There is no migration today or after Allah's Messenger." (and completed his statement as above.)
وَقَالَ النَّضْرُ أَخْبَرَنَا شُعْبَةُ، أَخْبَرَنَا أَبُو بِشْرٍ، سَمِعْتُ مُجَاهِدًا، قُلْتُ لاِبْنِ عُمَرَ فَقَالَ لاَ هِجْرَةَ الْيَوْمَ، أَوْ بَعْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم مِثْلَهُ.
