It is reported that a man once came to ‘Abdullâh b. ‘Umar – Allâh be pleased with him – and said:
I love you for Allâh.
Ibn ‘Umar replied:
Then bear witness that I hate you for Allâh!
The man asked, “Why?”
He replied, “Because you sing in your adhân (call to prayer), and you take a wage [for calling it]!”
