Kwa hiyo, ikiwa sharti la uadilifu linatumika kwa shahidi, basi ni wazi kwamba linatumika zaidi kama sharti la kumteua Khalifa, kwa kuwa Khalifa yuko katika nafasi kubwa zaidi kuliko shahidi.
So if the condition of justice applies to a witness, it obviously applies even more as a condition for appointing of a Khalifah since the Khalifah is in an even greater position than the witness.
6. Lazima awe huru. Mtumwa anamilikiwa na bwana wake, kwa hiyo hana mamlaka ya kujiamulia nafsi yake mwenyewe. Basi, kwa sababu zaidi, hawezi kusimamia mambo ya wengine, wala hawezi kuchukua jukumu la kutawala watu.
6. He must be free. The slave is possessed by his master, so he does not have the authority to dispose of his own self. So, by greater reason, he cannot conduct the affairs of others and so cannot take charge of ruling over the people.
7. Lazima awe na uwezo wa kubeba majukumu ya Khilafah: Hii ni kwa sababu ni miongoni mwa mahitaji ya bay'ah, na hivyo bay'ah kwa mtu asiye na uwezo wa kubeba majukumu ya Khilafah ni batili. Hizi ndizo sharti za kumfanya Khalifah awe Khalifah wa Khilafah. Chochote kisicho katika sharti hizi saba hakifai kuwa sharti la mkataba, ingawa kinaweza kuwa miongoni mwa sharti za ubora iwapo kimetokana na matini sahihi, au kikiwa chini ya hukm iliyothibitishwa kwa matini sahihi. Hii ni kwa sababu ili sharti liwe sharti la mkataba, dalili yake inapaswa kujumuisha amri ya uhakika inayofanya ilazimu kwake. Kwa hiyo, ikiwa dalili haijumuishi amri ya uhakika, basi sharti hilo ni la ubora na si la mkataba. Hakuna dalili yenye amri ya uhakika iliyopokelewa kuhusu jambo lolote isipokuwa sharti hizi saba, kwa hiyo hizi peke yake ndizo sharti za mkataba. Sharti nyingine zilizomo katika dalili sahihi ni sharti za ubora tu. Kwa hiyo, si sharti la mkataba wa Khilafah kwamba Khalifah lazima awe mujtahid, kwa sababu hakuna matini sahihi kuhusu jambo hilo, na pia kwa sababu wajibu wa Khalifah ni kutawala, na hahitaji lazima kufanya ijtihad, kwani anaweza kuuliza kuhusu hukm, kufuata mujtahid na kupitisha sheria kulingana na maoni ya mujtahid huyo. Kwa hiyo si lazima awe mujtahid, ingawa ni bora; lakini ikiwa hakuwa mujtahid, Khilafah bado ingefungwa kwake. Pia, si sharti la mkataba wa Khilafah kwamba Khalifah lazima awe jasiri, au mwenye maono mazuri ya kuendesha mambo ya jamii na kusimamia maslahi yake. Hii ni kwa sababu hakuna hadithi sahihi iliyopokelewa kuhusu suala hili, wala halimo chini ya hukm ya shari'ah inayolifanya kuwa sharti la mkataba; ingawa ni bora Khalifah awe jasiri na mwenye busara na maono ya kina.
7. He must be capable to undertake the responsibilities of the Khilafah: This is because this is from the requirements of the bay’ah and therefore the bay’ah to one incapable to undertake the responsibilities of the Khilafah is invalid. These are the conditions of contracting the Khalifah to the Khilafah. Anything other than these seven conditions are not suitable to be a contracting condition though they may be from the conditions of preference if they are produced from sound texts, or if they came under a hukm proven by a sound text. This is so because in order for condition to be a condition of contract, its daleel should include a decisive demand that becomes a connotation for its obligation. So if the evidence does not include a decisive demand, then the condition is one of preference and not of contracting. No evidence including a decisive demand was reported other than these seven conditions, so they are alone the conditions of contract. Other conditions included in sound evidences are conditions of preference only. Therefore, it is not a condition of contract to the Khilafah that the Khalifah must be a mujtahid because there is no sound text on the matter, and also because the duty of the Khalifah is to rule and he does not necessarily need to make ijtihad since he can inquire about the hukm, follow a mujtahid and adopt laws according to the opinion of that mutjahid. It is therefore not necessary for him to be a mujtahid, although it is preferable; but if he were not a mutjahid, the Khilafah would still be contracted to him. Also it is not a contracting condition to the Khilafah that the Khalifah must be brave, or of the people of good vision to manage the affairs of the community and to conduct its interests. This is so because no sound hadith was reported on this issue and it does not come under a hukm shari’ which makes it a contracting condition; although it is preferable that the Khalifah be brave and carry deep insight and vision.
Pia si sharti la lazima katika uimamu wa Khilafah kwamba Khalifah lazima atoke katika kabila la Quraish. Kuhusu kilichopokewa kutoka kwa Mu‘awiya kwamba alisema: Nilimsikia Mtume wa Allah ﷺ akisema:
Also it is not a contracting condition for the Khilafah that the Khalifah must be from the Quraish. As for what was reported from Mu‘awiya that he said: I heard the Messenger of Allah (saw) saying:
