Aswad bin Hilal reported,

A man from his people reported that during the caliphate of Umar bin Khattab, he used to say, "Uthman will not die until he becomes caliph."We asked, "How do you know that?"He replied, "I heard the Messenger of Allah ﷺ say, 'Last night I saw in a dream as if three of my companions were being weighed. Abu Bakr was weighed and outweighed the scale, then Umar was weighed and outweighed the scale, then Uthman was weighed and our companion fell short, though he is righteous.'"

عن الأسود بن هلال

عن رجل من قومه قال: كان يقول خلافة عمر بن الخطاب: لا يموت عثمان حتى يستخلف، قلنا: من أين تعلم ذلك؟ قال: سمعت رسول الله ﷺ يقول: رأيت الليلة في المنام كأن ثلاثة من أصحابي وزنوا، فوزن أبو بكر، فوزن، ثم وزن عمر، فوزن، ثم وزن عثمان، فنقص صاحبنا، وهو صالح.
