Yahya related to me from Malik from Zayd ibn Aslam from Ata ibn Yasar that the Messenger of Allah ﷺ said, "All that will be left of prophecy after me are the mubashshirat." They said, "What are the mubashshirat, Messenger of Allah?" He said, "The true dream which a man who is salih sees - or which is shown to him - is a forty-sixth part of prophecy."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لَنْ يَبْقَى بَعْدِي مِنَ النُّبُوَّةِ إِلاَّ الْمُبَشِّرَاتُ فَقَالُوا وَمَا الْمُبَشِّرَاتُ يَا رَسُولَ اللَّهِ قَالَ الرُّؤْيَا الصَّالِحَةُ يَرَاهَا الرَّجُلُ الصَّالِحُ أَوْ تُرَى لَهُ جُزْءٌ مِنْ سِتَّةٍ وَأَرْبَعِينَ جُزْءًا مِنَ النُّبُوَّةِ
