It was narrated that 'Aishah said:

"They say that the Prophet ﷺ made a will for 'Ali,[1] but he called for a basin in which to urinate, then he went flaccid suddenly (and died), so how could he leave a will?!"

The Shaikh said: Azhar (one of the narrators) is Ibn Sa'd As-Samman.

[1] Meaning, appointing him as the Khalifah.

أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ أَنْبَأَنَا أَزْهَرُ، أَنْبَأَنَا ابْنُ عَوْنٍ، عَنْ إِبْرَاهِيمَ، عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، قَالَتْ يَقُولُونَ إِنَّ النَّبِيَّ ﷺ أَوْصَى إِلَى عَلِيٍّ لَقَدْ دَعَا بِالطَّسْتِ لِيَبُولَ فِيهَا فَانْخَنَثَتْ نَفْسُهُ وَمَا أَشْعُرُ فَإِلَى مَنْ أَوْصَى قَالَ الشَّيْخُ أَزْهَرُ هُوَ ابْنُ سَعْدٍ السَّمَّانُ .
