Hadith

Not desiring the wealth of people

Q: What is greed in Islam as the Prophet (sallallahu alaihi wasallam) said wealth without greed is a blessing and wealth with greed is not a blessing. So is earning more considered greed? 

I read somewhere that Ameerul Mumineen said that be moderate in earning. I don't know if it's authentic or not. If yes, should we earn moderate and not earn more?

A fabricated hadith regarding a dua at the time of azaan

Q: Is the following authentic to be read at the time of azaan: 

مَرْحَبَّا بِالْقَائِلِينَ عَدْلاً مرْحَبًا بِالصَّلَوةِ وَأَهْلاً

Khateeb Baghdadi (rahimahullah) reports in a narration that Nabi (sallallahu alaiyhi wasallam) has said that whoever says the above the moment the Muazzin proclaims the Azaan; 20 000 virtues are written down for him; 20 000 sins are forgiven; and 20 000 ranks are elevated for him. (Jaamia Al Hadeeth, As-Suyuti, Pg 313, Vol 7)
