Muadh was among the seventy-two Yathribites who journeyed to Makkah, one year before the Hijrah, and met the Prophet (Sallallahu Alayhi Wa sallam) at his house and later again in the valley of Mina, outside Makkah, at Aqabah. Here the famous second Aqabah Pledge was made at which the new Muslims of Yathrib, including some women, vowed to support and defend the Prophet Sallallahu Alayhi Wa sallam) at any cost. Muadh RA was among those who enthusiastically clasped the hands of the blessed Prophet (Sallallahu Alayhi Wa sallam) then and pledged allegiance to him. As soon as Muadh RA returned to Madinah from Makkah, he and a few others of his age formed a group to remove and destroy idols from the houses of the Mushrikeen in Yathrib. One of the effects of this campaign was that a prominent man of the city, Amr ibn al-Jumuh, became a Muslim.
When the noble Prophet (Sallallahu Alayhi Wa sallam) reached Madinah, Muadh ibn Jabal RA stayed in his company as much as possible. He studied the Qur’an and the laws of Islam until he became one of the most well-versed of all the companions in the religion of Islam. Wherever Muadh RA went, people would refer to him for legal judgements on matters over which they differed. This is not strange since he was brought up in the school of the Prophet (Sallallahu Alayhi Wa sallam) himself and learnt as much as he could from him. He was the best pupil of the best teacher. His knowledge bore the stamp of authenticity. The best certificate that he could have received came from the Prophet (Sallallahu Alayhi Wa sallam) himself when he said: “The most knowledgeable of my ummah in matters of Halal and Haram is Muadh ibn Jabal.”
One of the greatest of Muadh’s contributions to the Ummah of Muhammad (Sallallahu Alayhi Wa sallam) was that he was one of the group of six who collected the Qur’an during the lifetime of the Prophet, peace be upon him. Whenever a group of companions met and Muadh RA was among them, they would look at him with awe and respect on account of his knowledge. The Prophet (Sallallahu Alayhi Wa sallam) and his two Khalifahs after him placed this unique gift and power in the service of Islam.
After the liberation of Makkah, the Quraysh became Muslims en masse. The Prophet (Sallallahu Alayhi Wa sallam) immediately saw the need of the new Muslims for teachers to instruct them in the fundamentals of Islam and to make them truly understand the spirit and letter of its laws. He appointed Attab ibn Usay as his deputy in Makkah and he asked Muadh ibn Jabal RA to stay with him and teach people the Qur’an and instruct them in the religion. Sometime after the Prophet (Sallallahu Alayhi Wa sallam) had returned to Madinah, messengers of the kings of Yemen came to him announcing that they and the people of Yemen had become Muslims. They requested that some teachers should be with them to teach Islam to the people. For this task the Prophet (Sallallahu Alayhi Wa sallam) commissioned a group of competent Du’at (missionaries) and made Muadh ibn Jabal RA their amir.
He then put the following question to Muadh RA: “According to what will you judge?” “According to the Book of Allah,” replied Muadh. “And if you find nothing therein?” “According to the Sunnah of the Prophet of Allah.” “And if you find nothing therein?” “Then I will exert myself (exercise ijtEhad) to form own judgement.” The Prophet (Sallallahu Alayhi Wa sallam) was pleased with this reply and said: “Praise be to Allah Who has guided the messenger of the Prophet to that which pleases the Prophet.”
The Prophet (Sallallahu Alayhi Wa sallam) personally bade farewell to this mission of guidance and light and walked for some distance alongside Muadh RA as he rode out of the city. Finally he said to him: “O Muadh, perhaps you shall not meet me again after this year. Perhaps when you return you shall see only my mosque and my grave.” Muadh RA wept. Those with him wept too. A feeling of sadness and desolation overtook him as he parted from his beloved Prophet, peace and blessings of Allah be on him.
The Prophet’s (Sallallahu Alayhi Wa sallam) premonition was correct. The eyes of Muadh RA never beheld the Prophet (Sallallahu Alayhi Wa sallam) after that moment. The Prophet (Sallallahu Alayhi Wa sallam) passed away before Muadh RA returned from the Yemen. There is no doubt that Muadh wept when he returned to Madinah and found there was no longer the blessed company of the Prophet (Sallallahu Alayhi Wa sallam).
During the caliphate of Umar RA, Muadh RA was sent to the Banu Kilab to apportion their stipends and to distribute the Sadaqah of their richer folk among the poor. Also during the caliphate of Umar RA, the governor of Syria, Yazid ibn Abi Sufyan sent a message saying: “O Amir al-Mu’mineen! The people of Syria are many. They fill the towns. They need people to teach them the Qur’an and instruct them in the religion.” Umar RA thereupon summoned five persons who had collected the Qur’an in the lifetime of the Prophet, peace be upon him. They were Muadh ibn Jabal, ‘Ubadah ibn asSamit, Abu Ayyub al-Ansari, Ubayy ibn Ka’b and Abu adDardaa. He said to them: “Your brothers in Syria have asked me to help them by sending those who can teach them the Qur’an and instruct them in the religion. Please appoint three among you for this task and may Allah bless you. I can select three of you myself if you do not want to put the matter to the vote.” “Why should we vote?” they asked. “Abu Ayyub is quite old and Ubayy is a sick man. That leaves three of us.” “All three of you go to Homs first of all. If you are satisfied with the condition of the people there, one of you should stay there, another should go to Damascus and the other to Palestine.”
So it was that ‘Ubadah ibn as-Samit was left at Homs, Abu ad-Dardaa went to Damascus and Muadh RA went to Palestine. There Muadh RA fell ill with an infectious disease. As he was near to death, he turned in the direction of the Ka’bah and repeated this refrain: “Welcome Death, Welcome. A visitor has come after a long absence . . .” And looking up to heaven, he said: “O Lord, You know that I did not desire the world and to prolong my stay in it …O Lord, accept my soul with goodness as you would accept a believing soul…” He then passed away, far from his family and his clan, a Da’iy in the service of Allah and a MuhajEr in His path.
