Hadith: A man asked the Prophet (may Allah's peace and blessings be upon him): "When is the Hour?" He said: "What have you prepared for it?

عَنْ أَنَسٍ رَضِيَ اللَّهُ عَنْهُ:
أَنَّ رَجُلًا سَأَلَ النَّبِيَّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ عَنِ السَّاعَةِ، فَقَالَ: مَتَى السَّاعَةُ؟ قَالَ: «وَمَاذَا أَعْدَدْتَ لَهَا». قَالَ: لاَ شَيْءَ، إِلَّا أَنِّي أُحِبُّ اللَّهَ وَرَسُولَهُ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ، فَقَالَ: «أَنْتَ مَعَ مَنْ أَحْبَبْتَ». قَالَ أَنَسٌ: فَمَا فَرِحْنَا بِشَيْءٍ، فَرِحْنَا بِقَوْلِ النَّبِيِّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ: «أَنْتَ مَعَ مَنْ أَحْبَبْتَ» قَالَ أَنَسٌ: فَأَنَا أُحِبُّ النَّبِيَّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ وَأَبَا بَكْرٍ، وَعُمَرَ، وَأَرْجُو أَنْ أَكُونَ مَعَهُمْ بِحُبِّي إِيَّاهُمْ، وَإِنْ لَمْ أَعْمَلْ بِمِثْلِ أَعْمَالِهِمْ.

Anas (may Allah be pleased with him) reported:
A man asked the Prophet (may Allah's peace and blessings be upon him): "When is the Hour?" He said: "What have you prepared for it?" He said: "Nothing, except that I love Allah and His Messenger (may Allah's peace and blessings be upon him)." He said: "You will be with whom you love." Anas said: We did not feel more joyful than we did due to the Prophet's statement: "You will be with whom you love." Anas said: I love the Prophet (may Allah's peace and blessings be upon him) and Abu Bakr and ‘Umar, and I hope I will be with them by virtue of my love for them, even if I did not perform deeds like their deeds.

Explanation

A Bedouin man, among the dwellers of the desert, asked the Prophet (may Allah's peace and blessings be upon him) about the time of the Hour.
The Prophet (may Allah's peace and blessings be upon him) said to him: What righteous deeds have you prepared for it?
The questioner said: I have not prepared much deeds for it, except that I love Allah and His Messenger. He did not mention any other act of worship, be it by the heart, body, or property, for these are all branches of love dependent on it, and because true love motivates a person to strive to do righteous deeds.
Thereupon, the Prophet (may Allah's peace and blessings be upon him) said to him: You will be with whom you love in Paradise.
The Prophet's Companions greatly rejoiced at this good news.
Then, Anas (may Allah be pleased with him) informed that he loved the Prophet (may Allah's peace and blessings be upon him) and Abu Bakr and ‘Umar and hoped he would be with them, even though his deeds were not like their deeds.
