Hadith on Love: A person will be with those whom he loved on the Day of Resurrection

Anas ibn Malik reported: A Bedouin said to the Messenger of Allah, peace be upon him, “When is the Hour (Day of Judgment)?” The Messenger of Allah said, “What have you prepared for it?” He said, “Love for Allah and His Messenger.” He said, “You will be with those whom you love.”
[Sahih Muslim, Book 32, Number 6378]

عَنْ أَنَسِ بْنِ مَالِكٍ  أَنَّ أَعْرَابِيًّا قَالَ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَتَى السَّاعَةُ قَالَ لَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَا أَعْدَدْتَ لَهَا قَالَ حُبَّ اللَّهِ وَرَسُولِهِ قَالَ أَنْتَ مَعَ مَنْ أَحْبَبْتَ
