حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ ثَوْرٍ، قَالَ حَدَّثَنِي حَبِيبُ بْنُ عُبَيْدٍ، عَنِ الْمِقْدَامِ بْنِ مَعْدِيكَرِبَ، - وَقَدْ كَانَ أَدْرَكَهُ - عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ إِذَا أَحَبَّ الرَّجُلُ أَخَاهُ فَلْيُخْبِرْهُ أَنَّهُ يُحِبُّهُ ‏"‏ ‏.‏

Narrated Anas ibn Malik

A man was with the Prophet (ﷺ) and a man passed by him and said: Messenger of Allah! I love this man. The Messenger of Allah (ﷺ) then asked: Have you informed him? He replied: No. He said: Inform him. He then went to him and said: I love you for Allah's sake. He replied: May He for Whose sake you love me love you!
