“The Quran”

 

“Those who criticize the contributors among the believers concerning [their] charities and [criticize] the ones who find nothing [to spend] except their effort, so they ridicule them – Allah will ridicule them, and they will have a painful punishment.”  9:79
“O Prophet! It is the same, whether you ask forgiveness for them or not; even if you ask for their forgiveness seventy times, Allah is not going to forgive them: because they have disbelieved Allah and His Messenger. Allah does not guide those who are transgressors.”  9:80
