Najashi

Aṣ-ḥamah also spelt as Aṣ-ḥama (أَصْحَمَة), was the Negus (ٱلنَّجَاشِيّ) ruler of the Kingdom of Aksum who reigned from 614–630 C.E.. It is agreed by Muslim scholars that Najashi gave shelter to Muslim emigrants from Mecca, around 615–616 at Axum.

Reign
The Najashi reigned for almost 17 years from 614–630 CE. Nothing much is known about his personal life and reign rather than during his reign, Muslims migrated to Abyssinia and met the Najashi. According to a story recorded by the Muslim biographer Ibn Ishaq (c. 704–767), Muhammad's cousin, Ja'far ibn Abi Talib, told Najashi about the persecution they had faced at the hands of the Arab tribe of Quraysh. Najashi asked if they had with them anything which had come from God. Ja'far then recited a passage from Surat Maryam in the Quran, regarding Jesus in Islam and Maryam. When the Najashi heard it, he wept and exclaimed: "Verily, this (Quran) and what Isa brought (Gospel) has come from the same source of light."

According to Ibn Ishaq, Najashi then affirmed that he would never give up the Muslims. In fact, he converted to Islam before he went out to the Abyssinians who accused him of abandoning the state religion/their beliefs. He then asked what their beliefs were. Once they explained the Christian doctrine to him, he replied:

"This is exactly what I believe."

The Negus put his hand upon a parchment which was on his breast when he gave that reply. The parchment affirmed Allah's oneness and that Jesus was merely a slave of Allah and a Prophet. The Abyssinians were content and went away.

He died in 630 CE. Some Muslim sources indicate that the Islamic prophet Muhammad prayed an absentee funeral prayer (صَلَاة الْغَائِب‎) in Al-Baqi Cemetery, Madinah which is performed upon a dead Muslim if they die in a place with no Muslims to pray for the dead.
