Read surah Al-Maa'un

أَرَءَیۡتَ ٱلَّذِی یُكَذِّبُ بِٱلدِّینِ 

HAST THOU ever considered [the kind of man] who gives the lie to all moral law?

فَذَ ٰلِكَ ٱلَّذِی یَدُعُّ ٱلۡیَتِیمَ 

Behold, it is this [kind of man] that thrusts the orphan away,

وَلَا یَحُضُّ عَلَىٰ طَعَامِ ٱلۡمِسۡكِینِ 

and feels no urge to feed the needy.

فَوَیۡلࣱ لِّلۡمُصَلِّینَ 

Woe, then, unto those praying ones

ٱلَّذِینَ هُمۡ عَن صَلَاتِهِمۡ سَاهُونَ 

whose hearts from their prayer are remote

ٱلَّذِینَ هُمۡ یُرَاۤءُونَ 

those who want only to be seen and praised,

وَیَمۡنَعُونَ ٱلۡمَاعُونَ 

and, withal, deny all assistance [to their fellow-men]!
