Arabic (Original)
حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ عَنْ عِمْرَانَ عَنْ قَتَادَةَ عَنْ أَنَسٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَتَبَ إِلَى كِسْرَى وَقَيْصَرَ وَأُكَيْدِرِ دُومَةَ يَدْعُوهُمْ إِلَى اللَّهِ عَزَّ وَجَلَّ.
English Translation
Anas reported that a man was with the Prophet (peace be upon him) when another man passed by. He said: "O Messenger of Allah, I love this man." The Prophet said: "Have you told him?" He said: "No." He said: "Tell him." So he caught up with him and said: "I love you for the sake of Allah." The man replied: "May the One for Whose sake you love me love you."
