When the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم was informed that a famous warrior of Najd (presently Riyadh), Du’soor Bin Haaris Muhaaribi, had gathered an army to attack Madinah, he صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم, along with the army of 400 blessed companions, went to fight against them. When Du’soor heard that the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم has arrived in his city, he ran away and climbed the mountains along with his army. One of his soldiers whose name was Habbaan was arrested and embraced Islam in the blessed court of the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم.
Suddenly, it rained heavily on that day. The Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم began to dry his clothes near a tree. From the top of the mountain, non-Muslims noticed that blessed companions were busy in their activities and he صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم was alone. Therefore, they incited Du’soor to attack the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم. Saying this sentence, ‘May I be killed by Allah if I am unable to kill Muhammad (صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم)’, he moved towards the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم with a sword in his hand and spoke raising the sword over the head of the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم. ‘Now, who will save you from me?’ He صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم replied: ‘Merciful Allah عَزَّوَجَلَّ will save me from you.’ He صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم had just said these words Sayyiduna Jibraeel عَـلَيْـهِ الـسَّـلَام immediately landed on the earth and gave Du’soor a punch on his chest, causing the sword to fall from his hand on the ground. The Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم immediately picked up the sword and then asked, ‘Now who will save you from me?’ Du’soor replied, ‘No one can save me from you!’
The Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم had mercy on his helplessness. He صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم did not only forgive his mistake, but he صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم also returned his sword to him. Du’soor was so much impressed with the merciful manners of the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم that he recited Kalimah and embraced Islam immediately. Having returned to his people, he started preaching Islam. (Al-Mawahib-ul-Ladunniyyah, vol. 2, pp. 378-381)
