There are many approaches, one could be the following:
Adding a class to all the buttons to group them, store their values (id and original text) and bind click events to them as follow:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="p-5">
  <button class="button" id="button1">Button 1</button>
  <button class="button" id="button2">Button 2</button>
  <button class="button" id="button3">Button 3</button>
  <button class="button" id="button4">Button 4</button>
  <p id="status" class="py-3"></p>
</div>
<script type="text/javascript">
        $(function () {
            let buttons = $('.button'), buttonValues = [];
            buttons.each(function() {
                let button = $(this);
                buttonValues.push({
                    id: button.attr("id"),
                    text: button.text()
                });
            });

            buttons.click(function() {
                let id = $(this).attr("id");
                
                let storedText = buttonValues.find(item => item.id === id).text;
                
                buttons.each(function() {
                    let button = $(this);
                    button.prop('disabled', false);
                    let originalText = buttonValues.find(item => item.id === button.attr("id")).text;
                    button.text(originalText);
                });

                $(this).prop('disabled', true);
                $(this).text('Selected');

                $("p").text(`You have clicked on ${storedText}`);
            });
});
    </script>

you have to detect which button is disabled, to acheive that you can either iterate over all button or save the disabled button in a global variable.

when you click a button start by enabling the disabled button, do your logic then disable the clicked button
```
let disabled;

$("#button1").click(function () {
    $("#button1").prop("disabled", true);
    $("p").text("You have clicked on Button 1");
    $(this).text("Selected");

     // enable the disabled one
    if(disabled) $(disabled).prop("disabled", false);

     // or find the disabled button then enable it
     document.querySelector("[disabled=true]")?.setAttribute("disabled", false);

    // now save our button as disabled
    disabled = "#button1";

  });
```

You are repeating your code, which is not good design (see DRY)

Instead I would recommend you take advantage of classes…

give each of your buttons the same class
give each of your buttons a data attribute to separate them
use a single event handler, rather than one each

$(function () {
  $(".mybutton").click(function () {
    // Enable all buttons
    let $all = $(".mybutton").prop("disabled", false);
    // Reset text on each button
    $all.each((i, x) => $(x).text(`Button ${$(x).data("buttonid")}`));
    // Disable THIS button, and say it's selected
    let $btn = $(this).prop("disabled", true).text("Selected");
    // Set the hint
    $("p").text(`You have clicked on Button ${$btn.data("buttonid")}`);
  });
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="p-5">
  <button id="button1" class="mybutton" data-buttonid="1">Button 1</button>
  <button id="button2" class="mybutton" data-buttonid="2">Button 2</button>
  <button id="button3" class="mybutton" data-buttonid="3">Button 3</button>
  <button id="button4" class="mybutton" data-buttonid="4">Button 4</button>
  <p id="status" class="py-3"></p>
</div>

As can be seen by the other answers, there are many ways to do what you want. One method that requires limited changes to your logic/code, is for each of your event handlers to call a function that enables all the buttons. That’s it! Add one short enableAll() function and call it at the beginning of each handler. See working code snippet below:

function enableAll( ) {
  $("#button1").prop("disabled", false);
  $("#button2").prop("disabled", false);
  $("#button3").prop("disabled", false);
  $("#button4").prop("disabled", false);
}
$(function () {
  $("#button1").click(function () {
    enableAll();
    $("#button1").prop("disabled", true);
    $("p").text("You have clicked on Button 1");
    $(this).text("Selected");
  });
  $("#button2").click(function () {
    enableAll();
    $("#button2").prop("disabled", true);
    $("p").text("You have clicked on Button 2");
    $(this).text("Selected");
  });
  $("#button3").click(function () {
    enableAll();
    $("#button3").prop("disabled", true);
    $("p").text("You have clicked on Button 3");
    $(this).text("Selected");
  });
  $("#button4").click(function () {
    enableAll();
    $("#button4").prop("disabled", true);
    $("p").text("You have clicked on Button 4");
    $(this).text("Selected");
  });
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="p-5">
  <button id="button1">Button 1</button>
  <button id="button2">Button 2</button>
  <button id="button3">Button 3</button>
  <button id="button4">Button 4</button>
  <p id="status" class="py-3"></p>
</div>

Here is a condensed way to do this. I used vanilla JS and jQuery. I’m sure you can condense it even more. If you use vanilla js you don’t need to add the jquery library

Vanilla JS

(function(){
    let buttonList = document.querySelectorAll('[id*=button]'),
    status = document.getElementById('status');

    buttonList.forEach(button => button.addEventListener('click', handleButton));

    function handleButton() {
        resetState();
        this.setAttribute('disabled', '');
        status.textContent = 'You have clicked ' + this.textContent;
    }

    function resetState() {
        buttonList.forEach(button => button.removeAttribute('disabled'))
    }
})()

jQuery

$(function(){
    $('[id*=button]').on('click', handleButton);

    function handleButton() {
        $(this).parent().children().removeAttr('disabled');
        $(this).prop('disabled', true);

        $('#status').text('You have clicked ' + $(this).text())
    }
})

An other way…
… shorter code in pure JS ?

const pStatus = document.querySelector('p#status')
  ;
document
.querySelectorAll('button[data-txt]')
.forEach( (btn,_,buttons_All) =>
  {
  btn.onclick =_=>
    {
    buttons_All.forEach( b => b.disabled = (b === btn) );
    pStatus.textContent = `You have clicked ${btn.dataset.txt}`;
    } 
  })

button[data-txt]::before {
  content: attr(data-txt);
  }
button[data-txt]:disabled::before {
  content: 'Selected';
  }

<div class="p-5">
  <button id="button1" data-txt="Button 1"></button>
  <button id="button2" data-txt="Button 2"></button>
  <button id="button3" data-txt="Button 3"></button>
  <button id="button4" data-txt="Button 4"></button>
  <p id="status" class="py-3"></p>
</div>
