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]!”
