Ahl al-Hadith Mu'adz bin Jabal Radhiyallahu 'anhu
Muadz bin Jabal bin Amr bin Aus al-Khazraji, with the nickname "Abu Abdurahman", was born in Medina.
He embraced Islam at the age of 18, He has the privilege of being a very intelligent and highly dedicated person. Physically, he is brave and powerful. God also blessed him with the ability to speak and speak beautifully, Muadz was included in the group of around 72 people from Medina who came to pledge allegiance to the Messenger of Allah. After that, Muadz returned to Medina as an Islamic preacher in the community of Medina. He succeeded in converting some prominent companions to Islam such as Amru bin Al-Jamuh.
When the Prophet Muhammad migrated to Medina, Muaz was always with the Prophet so that he could understand the Qur'an and Islamic laws well. This made him later appear as the most expert on the Qur'an among the Companions.
He is the person who reads the Qur'an the best and understands the laws of Allah the best. That is why the Messenger of God praised him by saying, "I mean the most knowledgeable of my people about halal and haram is Muaz bin Jabal." (Hadith Tirmidhi and Ibn Majah).
He narrated hadith from Abdullah bin Abbas, Abdullah bin Umar and narrated from him is Anas bin Malik, Masruq, Abu Thufail Amir bin Wasilah. In addition, Muadz was one of the six people who collected the Qur'an during the time of the Prophet.
After the city of Makkah was visited by the Messenger of Allah, the people of Makkah needed teachers who stayed with them to teach Islamic religious law. The Prophet then agreed to the request and requested that Muaz stay with the people of Makkah to teach the Qur'an and give them an understanding of the religion of God. His admirable nature was also clearly visible when a group of Yemeni kings came to meet the Prophet to declare their Islam and ask the Prophet to send them teachers. Even so, the Messenger of Allah chose Muaz to hold that task together with some of the companions.
Rasulullah sallallaahu alaihi wassalam related him to Abdullah bin Mas'ud. The Prophet sent him to Yemen to teach, provide religious knowledge and educate the Yemeni people until they memorized the Koran. Rasulullah sent him on foot while Mu'adz drove, and the Prophet said to him: "Truly, I love you".
Then he bequeathed to Muadz by saying: "O Muadz! It's possible that you won't be able to meet me again after this year", then Muadz cried because he was too sad to part with Rasulullah Sallallahu alaihi wassalam. After the event, it turned out that the Prophet died and Muadz could no longer see him. Muadz was very saddened by the death of the Messenger of Allah, may God bless him and grant him peace. He even cried sobbing for a few seconds. But he soon realized the responsibility of preaching on his shoulders. He always keeps his passion for Islam so that it does not wane. After Umar bin Khattab was appointed caliph, he sent Muaz to reconcile the dispute that occurred among the Kilab tribe. He successfully carried out the mission.
During the reign of Caliph Umar, the governor of Sham (now Egypt) sent Yazid bin Abi Sofian to ask for a teacher for his people. Then Umar called Muaz bin Jabal, Ubaidah bin As-Somit, Abu Ayub Al-Ansary, Ubai bin Kaab and Abu Darda' in an assembly. Caliph Umar said to them: "Indeed, your brothers in the land of Sham have asked for help from me to send anyone who can teach them the Qur'an and give them an understanding of the religion of Islam. Therefore, help me to get three people from among you, may God have mercy on you. If you want to vote, you can vote, otherwise I will appoint three people from among you." Then they answered: "We will not hold a vote considering that Abu Ayub is too old, while Ubai is always in pain, and there are only three of us left." Then Umar said to them: "You start working in Hims, if you like the condition of the people, one of you can live there. Then one of you should go to Damascus, and the other to Palestine." Then the three of them went out to Hims and they left Ubaidah bin As-Somit there, Abu Darda' went to Damascus. Muaz bin Jabal continued to go to the country of Jordan. Muaz bin Jabal was in Jordan at a time when the country was in the midst of an epidemic of infectious diseases.
Mu'adz bin Jabal died in 18 AH when there was a great epidemic in Urdun, at that time he was 33 years old.
