Kumbe chuki kubwa walio nayo hawa Waislam kwa Wayahudi na Wakristo ni kwasababu Mtume Marehemu Muham-mad, aliuwawa na mwanamke wa kiyahudi tena kwa sumu iliyochanganywa na nyama ya Mbuzi.

Ibn Sa'd page 249:
Verily a Jewish woman presented poisoned (meat of) a she goat to the apostle of Allah. He took a piece form it, put it into his mouth, chewed it and threw it away. Then he said to the Companions: "Halt! Verily, its leg tells me that it is poisoned." Then he sent for the Jewish woman and asked her; "What induced you to do what you have done?" She replied, "I wanted to know if you are true; in that case Allah will surely inform you, and if you are a liar I shall relieve the people of you."

Tabari Volume 8, page 124: [different narrator]
The messenger of God said during the illness from which he died - the mother of Bishr had come in to visit him - "Umm Bishr, at this very moment I feel my aorta being severed because of the food I ate with your son at Khaybar." 

Maswali:
If Marehemu Muham-mad was a real prophet of God, why didn't he catch the poison before he ate it?

If you believe that it was God's will for Marehemu Muham-mad to have eaten the poison, along with Bishr, why then did Muham-mad try to get well? Even Gabriel prayed for Muham-mad to get better, but Allah didn't answer that prayer either.

Hitimisho:
Marehemu Muham-mad was not a real prophet, he was a false prophet. He died as a result of eating poison that he didn't know about. The poisoned lamb "spoke" to him too late. Only when he realized he was dying did Marehemu Muham-mad "spiritualize" his suffering and coming death. Prior to that he tried to get well.
