Ikrimah bin Ibrahim narrates with his chain that the Messenger of Allah (peace and blessings be upon him) was asked about "Those who are heedless of their prayer" [Surah al-Ma'un: 5], "woe to those who are neglectful of the prayer", and he (peace and blessings be upon him) said: "It refers to wasting the time."
This hadith is only authentic as mawquf (stopping at the Companion), and Ikrimah bin Ibrahim was declared weak by Yahya bin Ma'in and other imams of hadith.
