Kuhusu Sunnah, Mjumbe wa Mwenyezi Mungu (ﷺ) mwenyewe alisimamia mahakama, na alihukumu baina ya watu. Al-Bukhari amesimulia kutoka kwa A'isha, mke wa Mjumbe wa Mwenyezi Mungu (ﷺ), kwamba alisema: "Utba Ibnu Abi Waqqas alimwambia nduguye Sa'd bin Abi Waqqas kwamba mtoto wa Zuma'a ni wake, hivyo mchukue na umweke kwako. Katika mwaka wa ushindi, Sa'd alimchukua na akasema: 'Mtoto huyu ni mpwa wangu, na (nduguye) amemkabidhi kwangu.' Abd ibn Zuma'a akasimama na kusema: 'Ni ndugu yangu, mwana aliyezaliwa na baba yangu, na alizaliwa kitandani kwake.' Wote wawili wakaenda kwa haraka kwa Mjumbe wa Mwenyezi Mungu (ﷺ), na Sa'd akasema: 'Ee Mjumbe wa Mwenyezi Mungu! Huyu ni mpwa wangu, na nduguye amenikabidhi,' na Abd bin Zuma'a akasema: 'Ni ndugu yangu, na mwana aliyezaliwa na baba yangu kitandani kwake.' Mjumbe wa Mwenyezi Mungu (ﷺ) akasema: 'Mtoto ni wa kitanda, na mzinzi apigwe mawe.'"
Mjumbe wa Mwenyezi Mungu (ﷺ) alikuwa akiwateua mahakimu. Aliamteua 'Ali kuwa hakimu juu ya Yemen, na alimpa maelekezo juu ya jinsi ya kuhukumu kwa kusema: "Watu wawili wenye mzozo wakikujia, usitoe hukumu kwa mmoja wao mpaka umesikia alichosema mwingine." Pia alimteua Mu'az kuwa hakimu juu ya Al-Janad. Hii inaonyesha urithi wa mahakama. Kuhusu namna ya kuhukumu iliyofanywa na Mjumbe (ﷺ), inaweza kutolewa kutoka Hadith ya 'A'iesha kwamba Sa'd na Abd Ibnu Zuma'a walizozana juu ya mtoto wa Zuma'a. Kila mmoja alidai kwamba ni wake. Mjumbe wa Mwenyezi Mungu (ﷺ) aliwajulisha hukumu ya Mwenyezi Mungu kwamba mtoto wa Zuma'a ni ndugu yake Abd Ibnu Zuma'a, na kwamba mtoto ni wa yule ambaye kitandani kwake alizaliwa. Kwa hiyo, hukumu yake (ﷺ) ilikuwa ni kutoa taarifa ya hukumu ya Mwenyezi Mungu, kisha akaitekeleza juu yao, na hivyo 'Abd Ibnu Zuma'a akamchukua mtoto. Hii ndiyo dalili inayotoa maana ya mahakama, na maana hii inatumika kama maelezo ya uhalisia. Hata hivyo, kwa kuwa hili ni uhalisia wa kimungu, na kwa kuwa ufafanuzi wa kimungu kwa kweli ni kanuni ya kimungu, basi unahitaji ushahidi ambao unapatikana kutokana nao, na Hadith hii inatumika kama ushahidi wa ufafanuzi wa uongozi wa kimahakama.
As for the Sunnah, the Messenger of Allah (pbuh) was himself in charge of the Judiciary and He judged between people. Al- Bukhari narrated about A’isha, wife of the Messenger of Allah (pbuh), that she said; “Utba Ibnu Abi Waqqas told his brother Sa’d bin Abi Waqqas that the child of Zuma’a belongs to him, so keep Him with you. In the year of the conquest, Sa’d took Him and said, ‘The child is my nephew, and He (his brother) has entrusted Him to me.’ Abd ibn Zuma’a stopped and said, ‘He is my brother, the son born to my father, and He was born on his bed.’ So they both rushed to the Messenger of Allah (pbuh) and Sa’d said ‘O Messenger of Allah! He is my nephew and my brother has entrusted Him to me’ and ‘Abd bin Zuma’a said, ‘He is my brother and a son born to my father on his bed.’ The Messenger of Allah (pbuh) said, ‘The child is for the bed and for the fornicator is stoning.’” The Messenger of Allah (pbuh) used to appoint the judges. He appointed ‘Ali as judge over Yemen and He gave Him instructions about how to judge by saying; “If two disputing men come to you do not give a judgement for one of them until you have heard what the other has had to say.” He (pbuh) also appointed Mu’az as a judge over Al-Janad. This indicates the legacy of the judiciary. As for the method of judicature carried out by the Messenger (pbuh), it can be deduced from the Hadith of ‘A’iesha that Sa’d and Abd Ibnu Zuma’a disputed over the son of Zuma’a. Each one claimed that He was his. The Messenger of Allah (pbuh) informed them of the divine rule that the son of Zuma’a was the brother of Abd Ibnu Zuma’a, and that the child belongs to the one on whose bed it is born. Therefore, his (pbuh) judgement was information about the divine rule and then He enforced it upon them, and thus ‘Abd Ibnu Zuma’a took the child. This is the evidence that gives the definition of the Judiciary and this definition serves as a description of the reality. However, since it is a divine reality, and since the divine definition is in fact a divine rule, it therefore requires evidence from which it is to be deduced, and this Hadith serves as an evidence for the definition of the judiciary.
