A man, or an Arabi, came to the Prophet ﷺ and asked, "Messenger of Allah, when will the Hour come?"The Prophet ﷺ replied, "What have you prepared for it?"The man said, "I have not prepared anything for it, except that I love Allah and His Messenger."The Prophet ﷺ said, "You will be with those whom you love."Anas said, "I have never seen the Muslims rejoice over anything, after embracing Islam, more than they rejoiced that day."

جاء رجل أو أعرابي إلى النبي ﷺ فقال يا رسول الله متى الساعة قال وما أعددت لها قال ما أعددت لها إلا أني أحب الله ورسوله فقال أنت مع من أحببت قال أنس فما رأيت المسلمين فرحوا بشيء بعد الإسلام أشد ما فرحوا يومئذ
