[Machine] The Messenger of Allah ﷺ said, "I entered Paradise last night and I saw that Ja'far was flying with the angels, and Hamza was lying on a couch." The Hadith has a Sahih (authentic) chain of narration and Salamah ibn Wahram did not consider it weak according to Abu Dawud.
قَالَ رَسُولُ اللَّهِ ﷺ «دَخَلْتُ الْجَنَّةَ الْبَارِحَةَ فَنَظَرْتُ فِيهَا فَإِذَا جَعْفَرٌ يَطِيرُ مَعَ الْمَلَائِكَةِ وَإِذَا حَمْزَةُ مُتَّكِئٌ عَلَى سَرِيرٍ» صَحِيحُ الْإِسْنَادِ وَلَمْ يُخَرِّجَاهُ سلمة بن وهرام ضعفه أبو داود
