“Waziri wangu wawili duniani ni Abu Bakr na Umar” (ameripotiwa na Al-Hakim na Al-Tirmidhi kutoka kwa Abu Said Al-Khudri). Hadithi hii imetumiwa na Mafaqihi na imekubaliwa na wanazuoni wengi, hivyo ni hadithi Hasan, na kwa hiyo ni dalili ya Shari'ah kwamba Khalifah anaweza kuteua wasaidizi. Hadithi imetumia neno “waziri” kwa maana ya kiisimu, yaani msaidizi, na Qur'ani inalitumia kwa maana hiyo; Allah (swt) amesema: “Na nipe waziri kutoka familia yangu” (TMQ 20:29), yaani msaidizi. Uwaziri ulikuwepo wakati wa Mtume (ﷺ), na ushahidi wake ni maandishi ya hadithi kutoka kwa Al-Tirmidhi. Hata hivyo, Mtume (ﷺ) ndiye aliyekuwa akitawala, na hakuna kinachoonyesha kwamba alimfanya Abu Bakr (ra) na Umar (ra) watekeleze alichokuwa akitekeleza katika utawala; lakini kuwafanya kuwa mawaziri kunaonyesha kwamba aliwaagiza wamsaidie; yaani, aliwaagiza wote wawili watekeleze alichokuwa akifanya katika utawala. Baada ya kifo cha Mtume (ﷺ), Umar (ra) alikuwa waziri wa Abu Bakr (ra), na alikuwa akitekeleza yale ambayo Khalifah alikuwa akiyatekeleza katika utawala, na jambo hilo lilikuwa wazi kiasi kwamba baadhi yao walikuwa wakimwambia Abu Bakr (ra), “Hatujui kama Umar ndiye Khalifah au wewe” ameripotiwa na Ibn Hanbal katika Fada'il Al-Sahabah kutoka kwa Nafi'. Baada ya kifo cha Abu Bakr (ra), 'Uthman (ra) na 'Ali (ra) walikuwa mawaziri wa Umar (ra), na kila mmoja wao alitekeleza yale ambayo Umar (ra) alifanya katika utawala, isipokuwa kwamba nguvu ya haiba ya Umar (ra) ilifanya vitendo vya usaidizi vya mawaziri hao wawili visionekane kwa uwazi kama vile vya Umar (ra) pamoja na Abu Bakr (ra), ingawa kutokana na nguvu ya haiba ya 'Ali (ra), ilikuwa wazi kwamba alitekeleza vitendo hivyo wakati wa Umar (ra). Baada ya kifo cha Umar (ra), 'Ali (ra) na Marwan b. Al-Hakam (ra) walikuwa mawaziri wawili wa 'Uthman (ra). Hata hivyo, 'Ali (ra) hakuridhika na baadhi ya matendo, kwa hiyo kazi yake pamoja na 'Uthman (ra) haikuonekana sana kwa kuwa alifanana na mtu aliyejitenga. Kwa upande mwingine, Marwan (ra) alionekana wazi katika kushika wadhifa huo, yaani, katika matendo ya kutawala.
“My two ministers in the World are Abu Bakr and Umar” (reported by Al-Hakim and Al-Tirmidhi from Abu Said Al-Khudri). This narration has been used by the Fuqaha’ and has been accepted by most of the scholars, so it is a Hasan narration and accordingly is a Shari’ah evidence that the Khalifah can appoint assistants. The narration used the word “minister” in the linguistic meaning, which is assistant, and the Quran uses it with this meaning; Allah (swt) said. “And appoint for me a minister from my family.” (TMQ 20:29), in other words, an assistant. And the ministry was present during the time of the Messenger (pbuh) , and its proof is the text of the narration from Al-Tirmidhi. However, it was the Messenger (pbuh) who was the one who ruled, and there is nothing which indicates that he made Abu Bakr (ra) and Umar (ra) carry out what he did from ruling, but making them into ministers indicates that he commissioned them to assist him; in other words, commission for both of them to carry out what he did from ruling. After the death of the Messenger (pbuh) , Umar (ra) was the minister of Abu Bakr (ra), and used to carry out what the Khalifah used to carry out in terms of ruling, and that was apparent to the point that some of them used to say to Abu Bakr (ra), “We don’t know whether Umar is the Khalifah or you” reported by Ibn Hanbal in Fada’il Al-Sahabah from Nafi’. After the death of Abu Bakr (ra), ’Uthman (ra) and ’Ali (ra) were the ministers of Umar (ra), and each of them carried out what Umar (ra) did in terms of ruling, except that the power of the personality of Umar (ra) meant that the actions of assistance of the two ministers were not so apparent as that of Umar (ra) with Abu Bakr (ra), although due to the power of the personality of ’Ali (ra), it was clear that he carried out these actions in the time of Umar (ra). After the death of Umar (ra), ’Ali (ra) and Marwan b. Al- Hakam (ra) were the two ministers of ’Uthman (ra). However, ’Ali (ra) was not content with some of the actions, and so his work with ’Uthman (ra) was not prominent since he was similar to someone withdrawn. On the other hand, Marwan (ra) was apparent in his undertaking of the ministry, in other words, the actions of ruling.
