Condemnation of Riya

Abu Hurairah (RA) narrates: I heard Rasulullah (SAW) saying:

The first amongst the people against whom judgement will be pronounced on the Day of Resurrection will be a martyr. He will be brought forward. Allah will remind him of his favours and he will acknowledge them. Allah Ta'ala will ask: What did you do (to show graditude) for these favours? He will reply: I fought for You till I was martyred. Allah will say: You have lied; you fought to be called brave, so it has been said. Command will then be issued about him. He will be dragged on his face, until cast into the Fire.

Next, a man who had learnt and taught (religious) knowledge and recited the Qur'an, he will be brought forward. Allah will remind him of His favours and he will acknowledge them. Allah Taala will ask: What did you do (to show graditude) for this favours? He will reply: I learn and taught (religious) knowledge and recited the Qur'an for your sake. Allah Taala will say: You have lied, you acquired knowledge to be called learned, and you recited the Qur'an to be called Qari (reciter of the Qur'an); so you have been called such. Command will then be issued about him. He will be dragged on his face, until cast into Fire.

Next a man whom Allah Taala had made wealthy and to whom He had given all kind of riches, will be brought forward. Allah Ta'ala remind him of His favours and he will acknowledge them. Allah Ta'ala will ask: What did you do (to show graditude) for this favours'? He will reply: I left no cause in which You like money to be spend, except that I spent in it for Your sake. Allah Ta'ala will say: You have lied; you did so to be called generous, so it has been said. Command will then be issued about him. He will be dragged on his face and cast into the Fire.
