Abu Hurairah reported,

The Prophet ﷺ said, "A man set out to visit a brother of his in another village. Allah stationed an angel along his path. When the man came upon him, the angel asked, 'Where are you headed?'The man replied, 'I am going to see a brother of mine in this village.'The angel asked, 'Do you have some favor from him that you wish to repay?'He said, 'No, I love him only for the sake of Allah عز وجل.'The angel said, 'Then I am Allah's messenger to you, sent to tell you that Allah loves you just as you love him for His sake.'"

عن أبي هريرة

عن النبي ﷺ قال: إن رجلا زار أخا له في قرية أخرى، فأرصد الله له على مدرجته ملكا، فلما أتى عليه قال: أين تريد؟ قال: أريد أخا لي في هذه القرية. قال: هل لك عليه من نعمة تربها؟ قال: لا، غير أني أحببته في الله عز وجل. قال: فإني رسول الله إليك، بأن الله قد أحبك كما أحببته.
