Abu Hurairah reported,

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

عن أبي هريرة

عن النبي ﷺ قال: أن رجلا زار أخا له 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 ﷺ إليك، بأن الله قد أحبك كما أحببته فيه.
