Hazrat Anas (Raziallahu Anhu) narrates that Rasulullah (Sallallahu Alaihi Wasallam) said: “That is the prayer of the hypocrite :
He sits watching the sun until it turns pale, then he gets up and hurriedly performs four Rakats in which he only remembers Allah a little.
(Sahih Muslim, Sunanut Tirmizi, Sunan Nasai)
Deliberately delaying Salah is a sign of weakness of Iman(faith). Delaying the Asr Salah till the time that the sun loses its brightness, unnecessarily, has been attributed to hypocrisy in the above hadith. Whilst the Salah performed in this manner is valid, One should not unnecessarily delay the Asr Salah. If one foresees a delay e.g. traffic, it should rather be performed before leaving.
