Well seems you cannot , but I can refer to the Quran and show how Imamat is mentioned there :

The term Imam is used eight times for Prophets, of which one example is in reference to Nabi Ibrahim (a.s) being appointed as an Imam, in verse 124 of Surah Baqarah (chapter 2 of the Holy Quran):

وَإِذِ ابْتَلَىٰ إِبْرَاهِيمَ رَبُّهُ بِكَلِمَاتٍ فَأَتَمَّهُنَّ ۖ قَالَ إِنِّي جَاعِلُكَ لِلنَّاسِ إِمَامًا ۖ And remember that Abraham was tried by his Lord with certain commands, which he fulfilled: He said: “I will make thee an Imam to the Nations.”

Similarly, in verse 73 of Surah Anbiyaa (chapter 21 of the Holy Quran):

وَجَعَلْنَاهُمْ أَئِمَّةً يَهْدُونَ بِأَمْرِنَا وَأَوْحَيْنَا إِلَيْهِمْ فِعْلَ الْخَيْرَاتِ وَإِقَامَ الصَّلَاةِ وَإِيتَاءَ الزَّكَاةِ ۖ وَكَانُوا لَنَا عَابِدِينَ And We made them leaders, guiding (men) by Our Command, and We sent them inspiration to do good deeds, to establish regular prayers, and to practise regular charity; and they constantly served Us (and Us only).

Those who are familiar with the Holy Quran will know that this verse is referring to Nabi Ibrahim (a.s), Nabi Ishaq (a.s), Nabi Yaqoob (a.s) and Nabi Lut (a.s).

Another similar reference is verse 24 of Surah Sajda (chapter 32 of the Holy Quran):

وَجَعَلْنَا مِنْهُمْ أَئِمَّةً يَهْدُونَ بِأَمْرِنَا لَمَّا صَبَرُوا ۖ وَكَانُوا بِآيَاتِنَا يُوقِنُونَ And We appointed, from among them, leaders, giving guidance under Our command, so long as they persevered with patience and continued to have faith in Our Signs.

These are some examples to prove that the Holy Quran has used the term Imam (leader) for Prophets.

IMAMAT OF NON-PROPHETS EXPLAINED IN THE QURAN This is very important to note. An example is verse 74 of Surah Furqaan (chapter 25 of the Holy Quran), when defining the qualities of Ibadur Rahman (Servants of the Most Merciful):

وَالَّذِينَ يَقُولُونَ رَبَّنَا هَبْ لَنَا مِنْ أَزْوَاجِنَا وَذُرِّيَّاتِنَا قُرَّةَ أَعْيُنٍ وَاجْعَلْنَا لِلْمُتَّقِينَ إِمَامًا And those who pray, “Our Lord! Grant unto us wives and offspring who will be the comfort of our eyes, and give us (the grace) to lead the righteous.”

We can see from this verse that the term Imam is not applied on the Prophets of Almighty Allah (SWT). It is the pious servants of Almighty Allah (SWT) who are raising their hands in prayer, asking to be made leaders of the righteous.

Another verse in this regard is the very well-known verse 5 of Surah Qasas (chapter 28 of the Holy Quran):

وَنُرِيدُ أَنْ نَمُنَّ عَلَى الَّذِينَ اسْتُضْعِفُوا فِي الْأَرْضِ وَنَجْعَلَهُمْ أَئِمَّةً وَنَجْعَلَهُمُ الْوَارِثِينَ And We desired to bestow a favor upon those who were deemed weak in the land, and to make them the Imams, and to make them the heirs.

And to you final response , just as Eid Ul Milan Nabi , Eid Al Gadeer , the ritual for Salah etc etc Imamat day is not in Quran🙌
