Hazrat ‘Aaishah (radhiyallahu ‘anha) reports that Najaashi’s father was the Emperor of Abyssinia. He had no other son besides Najaashi, while his brother (Najaashi’s uncle) had twelve sons.

Since Najaashi was the only son of his father, while the Emperor’s brother (Najaashi’s uncle) had many children, some of the people of Abyssinia thought of killing the Emperor and making his brother the Emperor. They felt that since his brother has many children, rulership will remain in the same family for a longer period of time. Hence, they killed the Emperor and made his brother the Emperor.
