that he رَضِىَ اللهُ تَعَالٰی عَنْهُ passed away in the sorrow and grief of Muṣṭafā صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم. Ibn-e-Sa’d and Ḥakīm have narrated from Ibn-e-Shaĥāb that the cause of the apparent passing of Sayyidunā Abū Bakr رَضِىَ اللهُ تَعَالٰی عَنْهُ was that once someone sent Khuzayraĥ [a type of mincemeat] as a gift to him. Sayyidunā Ṣiddīq Al-Akbar رَضِىَ اللهُ تَعَالٰی عَنْهُ and Ḥāriš Ibn-e-Kaladaĥ رَضِىَ اللهُ تَعَالٰی عَـنْهُ both partook in eating it.
After having eaten some of it, Ḥāriš, because he was a Ḥakīm, said, ‘O successor of Rasūlullāĥ! Stop your hand and refrain from eating this because there is poison in this. The effects of this poison become apparent within one year. You will see that both you and I will pass away on the same day within a year.’ Upon hearing this, he رَضِىَ اللهُ تَعَالٰی عَنْهُ moved his hand away from the food but the poison had done its work. Both of them remained ill from that day and after a year, they both passed away on the same day due to the effect of that poison. (Tārīkh-ul-Khulafā, p. 62)
This narration of Ḥākim as reported by Sha’abī is as follows, ‘What can we expect from this wretched world, in which even the Prophet of Allah صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم was given poison as was Ṣiddīq Al-Akbar رَضِىَ اللهُ تَعَالٰی عَنْهُ.’ (Tārīkh-ul-Khulafā, p. 62)
There is no contradiction in any of the above narrations [regarding the cause for the passing of Sayyidunā Abū Bakr
