حَدَّثَنَا حَسَنٌ حَدَّثَنَا ابْنُ لَهِيعَةَ حَدَّثَنَا أَبُو زُرْعَةَ عَمْرُو بْنُ جَابِرٍ عَنْ سَهْلِ بْنِ سَعْدٍ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ لَا تَسُبُّوا تُبَّعًا فَإِنَّهُ قَدْ كَانَ أَسْلَمَ.

Hasan narrated to us: Ibn Lahi'ah narrated to us: Abu Zur'ah 'Amr ibn Jabir narrated to us, from Sahl ibn Sa'd, who said: I heard the Messenger of Allah, peace and blessings be upon him, say: "Do not curse Tubba', for he had indeed accepted Islam."
