2:124 And [mention, O Muhammad], when Abraham was tried by his Lord with commands and he fulfilled them. [ Allah ] said, “Indeed, I will make you a leader for the people.” [Abraham] said, “And of my descendants?” [ Allah ] said, “My covenant does not include the wrongdoers.”
translation sahih international
imamat is in the descendants of abrahim a.s, in the light of quran imamat really exist with a very important role.And its a proof from quran so if anyone reject this ,then surely he had rejected the quran
21:73 And We made them Imams who guided (people) by Our command, and We revealed to them the doing of good and the keeping up of prayer and the giving of the alms, and Us (alone) did they serve
Imam means a person who is appointed by God as a leader and as a guide
its totally cleared by quran that allah made imam so why people dont know about the imam?What is the reason to reject it?Quran had aware them that allah made imam for guidence but only munafiq reject,s quran.
17:71 (Remember) the day when We will call every people with their Imam; then whoever is given his book in his right hand, these shall read their book; and they shall not be dealt with a whit unjustly.
Now i dont wanna say anything about those who dont believe on imam,s because quran say,s
(Remember) the day when We will call every people with their Imam,morons, never agree with anyone i just want ask one thing for those who don,t believe on quran ,my question is when allah will call everyone with their imam,s with whom will you come?
2:21] O men! serve your Lord Who created you and those before you so that you may guard (against evil).
Now my work is done ,i have provided the proof from quran that allah had made those before us that we get guard against evil and he had made imam,s for guidence ,now if still anyone dont wanna believe on imamat then he is rejecting quran means rejecting allah means that he dont believe on god from his heart and he is munafiq.Its is proved by quran ,,now the dont know about those who is for to guide us ?
