When the Messenger of Allah ﷺ finished the dawn prayer, he would ask: Did any of you have a dream last night? And he said: All that is left of Prophecy after me is a good vision. (Using translation from Abū Dāʾūd 5017)  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ إِذَا انْصَرَفَ مِنْ صَلَاةِ الْغَدَاةِ قَالَ «هَلْ أُرِيَ أَحَدٌ مِنْكُمُ اللَّيْلَةَ رُؤْيَا؟» وَيَقُولُ «إِنَّهُ لَيْسَ يَبْقَى بَعْدِي مِنَ النُّبُوَّةِ إِلَّا الرُّؤْيَا الصَّالِحَةُ»  

[Machine] The Messenger of Allah ﷺ used to be impressed by good dreams and he would say, "Has anyone among you seen a dream? Perhaps a man sees a dream and he asks about it, then when it is praised, it becomes more pleasing to him that he is a righteous man."  

كَانَتْ تُعْجِبُ رَسُولَ اللهِ ﷺ الرُّؤْيَا الْحَسَنَةُ وَيَقُولُ «هَلْ رَأَى أَحَدٌ مِنْكُمْ رُؤْيَا؟ فَرُبَّمَا رَأَى الرَّجُلُ رُؤْيَا فَيَسْأَلُ عَنْهُ فَإِذَا أُثْنِيَ عَلَيْهِ خَيْرًا كَانَ أَعْجَبَ إِلَيْهِ أَنْ يَكُونَ رَجُلًا صَالِحًا»  

"The Messenger of Allah ﷺ drew aside the curtain when he had a cloth wrapped around his head during his final illness, and said: 'O Allah, I have conveyed (the Message)' three times. 'There is nothing left of the features of Prophethood except a good dream that a person sees or is seen by others for him. But I have been forbidden to recite the Qur'an when bowing and prostrating, so when you bow, then glorify your Lord and when you prostrate, then strive hard in supplication, for it is more deserving of a response.'" (Using translation from Nasāʾī 1120)  

كَشَفَ رَسُولُ اللهِ ﷺ السِّتْرَ وَرَأْسُهُ مَعْصُوبٌ فِي مَرَضِهِ الَّذِي مَاتَ فِيهِ قَالَ «اللهُمَّ هَلْ بَلَّغْتُ؟» ثَلَاثَ مَرَّاتٍ «إِنَّهُ لَمْ يُبْقِ مِنْ مُبَشِّرَاتِ النُّبُوَّةِ إِلَّا الرُّؤْيَا الصَّالِحَةُ يَرَاهَا الْعَبْدُ أَوْ تُرَى لَهُ أَلَا فَإِنِّي نُهِيتُ عَنِ الْقِرَاءَةِ فِي الرُّكُوعِ وَالسُّجُودِ فَإِذَا رَكَعْتُمْ فَعَظِّمُوا وَإِذَا سَجَدْتُمْ فَاجْتَهِدُوا فِي الدُّعَاءِ فَإِنَّهُ قَمِنٌ أَنْ يُسْتَجَابَ لَكُمْ»
