Usaid ibn Hafeer picked up a weapon and moved towards them. When he came to them, Asad ibn Zurarah said to Musab, “This is the senior-most member of our community. If possible, convert him to Islam.” Musab said, “If hegives me some respite and listens to me, hopefully he would become a Muslim.”
Meanwhile Usaid ibn Hafeer had reached near them and he began to mouth whatever abuses came to his mind. He told them, “You have come to deviate the simple minded people of this tribe. For the sake of your life, get up at once and begone.” Musab said with utmostdignity and demeanor, “I have a request to you that you please sit down for a moment and listen to what I have to say. If you find my words acceptable, do accept them otherwise there is no problem if you choose otherwise.” No one knows what Usaid thought; hekept his weapon aside and sat down besides Musab.
Musab told him about the religion of Islam in brief and after that recited a few verses of Quran. The attractive statements about the principles of Islam and the eloquent words of Quran and that too from a youth of Mecca had such an effect that it melted theHeart of Usaid that he suddenly exclaimed, “What a beautiful and spiritual discourse it is!” Sparks of joy flickered in the eyes of Usaid. There was a complete transformation in his personality and
his thoughts also underwent a change. He asked, “What should one who desires to accept this religion do?” Musab replied, “He should perform a ritual bath, wear clean clothes, recite the testimony of faith and performtwo units (rakats) of prayer.”
Usaid ibn Hafeer did as directed and then said, “There are two persons behind me. If they accept faith none in the Aws tribe would turn away from Islam. I am going and I would send Saad ibn Mu’az to you.”
When Usaid returned to his tribesmen Saad ibn Mu’az looked at him and said, “Though Usaid has returned, his thinking is not the same as what it was when he had gone from here. He is looking completely transformed.” Then he asked Usaid what feat he had performed.Usaid replied, “I have warned them sternly and there is no danger from them anymore. Because I have threatened them so much about their mission that now they would do only as you say.”
After that Usaid said, “O Saad! When I was returning, I heard that a group of men from Bani Haritha are coming to murder Asad ibn Zurarah and break the treaty of peace.”
Saad ibn Mu’az got up at once, picked up his sword and rushed out thinking that Bani Haritha men may attack Asad ibn Zurarah before he could reach there. But when he reached the place where Musab and Asad were seated he found them safe and sound and no menfrom Bani Haritha were in sight. He at once realized the ruse of Usaid and spoke caustically to Asad, “If you had not been related to me, being my maternal aunt’s son, you would not have dared to perform that dangerous task which I dislike, in our own tribe.”
Again Musab resorted to the same mode of action that he had used with Usaid. Saad was also deeply affected. Therefore he also liked the simplicity of Islamic laws and the magnetic verses of Quran. Musab’s statements transformed his heart. He became a Muslimat that very moment. When Saad’s tribesmen saw him they remarked, “By Allah! Saad is not what he was before. He has changed completely.”
Saad came to his people and said, “O people of Bani Abdul Ashmal (another name of Bani Aws)! What is your opinion about me? What position do you accord me amongst yourself?” All replied in unison, “You are the senior-most person among us. You are better thanus in intelligence, integrity and purity.” After that Mu’az said, “Now I have the right to say that no man or woman from among you can speak to me till he or she has not accepted the religion of Islam.”The first ambassador of Rasulullah (sallallahu alaihiwasallam)was thus supremely successful. Rasulullah (sallallahu alaihi wasallam) had chosen well. Men and women, the young and the old, the powerful and the weak accepted Islam at his hands. The course of Yathribite history had been changed forever. The waywas being prepared for the great Hijrah. Yathrib was soon to become the center and the base for the Islamic state.
Asad ibn Zurarah and Musab says that it was such an auspicious day that before the sun set all the people of Aws and Khazraj tribes became Muslims. These two clans were the most powerful, influential and famous tribes of the Arabs. Thus their conversion toIslam meant that Islam became the dominant faith of Medina .
Musab and Asad returned from Saad’s residence and upon reaching home became engrossed in the propagation of religion. It is sufficient matter of Honor for Musab that with the help of Asad ibn Zurarah he succeeded in conveying the message of islam too, Two of most influential personalities of Medina , Usaid ibn Hafeer and Saad ibn Mu’az. When Musab stood up to pray the people of Medina accepted his leadership and the congregational prayers were performed in Medina for the first time. other peopleof Medina also participate in the congregational prayers. Since they Aws and Khazraj was the most influential and famous old tribes of medina, they and others agreed to the leadership of Musab and none had any objection because he was the representative ofRasulallah(sallallahu alayhi wa salam)and all who embraced Islam praying behind him.
Mus`ab stayed in Madinah for about a year then returned to Makkah during the season of pilgrimage. He took 75 Muslims fromMadinah known as Ansar (helpers) because they helped the Muslims from Makkah when they later migrated to Madinah. This group made a pledge of allegiance with Rasulullah (sallallahu alaihi wasallam)that they would defend him at all costs and remain firm in theirfaith. Shortly after this pledge, Rasulullah (sallallahu alaihi wasallam) directed his persecuted followers to migrate to Madinah.)(The first of the Sahabah to arrive there were Mus`ab and a blind old man named Abdullah ibn Umm Maktum.
In this way, much before the migration of Rasulullah (sallallahu alaihi wasallam)to Medina , Musab had converted the majority of the people of Medina to Islam with his foresight, intelligence and meritorious qualities.Musab had actually prepared the ground for Rasulullah's (sallallahu alaihi wasallam)arrival in Medina , and that is the reason that when Rasulullah (sallallahu alaihi wasallam) fled the dangerous situation of Mecca and reached Medina he received a hearty welcome.Upon his arrival at Medina he heaved a sigh of relief. Because it was a time when except for Medina every area of the Arabian Peninsula was aflame with the fire of polytheism and infidelity. It was due to the efforts of Musab Ibn Umair that Medina proved tobe a refuge for Rasulullah (sallallahu alaihi wasallam).
, the two tribes buried their mutual enmity after some time. It was because of Musab ibn Umayr, "the first ambassador of Islam", that at the Hijra: The next chapter of Mus`ab’s life wasthe battle of Badr. After this battle the Quraish prisoners of war were brought to Rasulullah (sallallahu alaihi wasallam) who put them into the custody of individual Muslims. They were ordered to treat the prisoners well. Among these prisoners was the brotherof Mus`ab named Abu `Aziz ibn `Umayr who told the story:“I was among a group of Ansar—whenever they had lunch or dinner they would give me bread and dates to eat in obedience to Rasulullah's (sallallahu alaihi wasallam) instructions to themto treat us well. My brother, Mus`ab passed by me and said to a man from the Ansar who was holding me prisoner: ‘Tie him firmly…His mother is a woman of great wealth and maybe she would ransom him for you.” Aziz couldn’t believe his ears. He turned to Mus`aband said, “My brother, is this your instruction concerning me?”
