Humility of al-Najashi
He said: Abul Husain Ahmad b. al-Husain b. Usamah al-Basriy has allowed me to narrate that Ubaidullah b. Muhammad al-Wasitiy reported form Abu Ja'far Muhammad b. Yahya, who reported from Harun b. Muslim b. Sa'dan, who reported from Mas'adah b. Sadaqah, who reported from Ja'far b. Muhammad, from his father, peace be upon them all, that:
Al-Najashi, the king of Abyssinia, sent for Ja'far b. Abu Talib and his companions. When they called upon him, they saw him sitting on the dusty ground, wearing old clothes. Ja'far b. Abu Talib said that when we saw him in that condition, we were taken by fear. But, upon sensing our concern and the change of colour in our faces, he said: "Praise be to Allah, Who helped Muhammad, peace be upon him and his progeny, and thus cooled and comforted my eyes! May I not give you good tidings?" I said: "Yes, O king." He said: "Just now, one of my informers in your lands has come to inform me that Allah helped His Prophet, Muhammad, peace be upon him and his progeny, and destroyed his enemy. And so-and-so has been taken prisoner and so-and-so has been killed. They had confronted each other at a place called Badr. As if I see him the way I used to tend my master's cattle there, who was from Banu Zamrah."
So Ja'far said to him: "O benign king! Why do I see you sit on the dust wearing the old attire?"
He said: "O Ja'far, we read in what has been revealed to Isa, may Allah bless him, that it is Allah's right over His servants that whenever He bestows a bounty upon them, they should show humility. So when Allah blessed Muhammad, His Prophet with the bounty, I profferred this humility before Him."
He said: When the Prophet, peace be upon him and his progeny, learnt about this, he said to his companions: "Giving away in charity and alms increases the wealth of its owner, so give alms, may Allah have mercy on you. And humility elevates and enhances the stature of the one who adopts it, so be humble, may Allah elevate you. And to be forgiving increases the honour of the forgiver. So be forgiving, that Allah may bless you with honour."
