Salat

Abdullah ibne -Amr rta narrates that one day, Prophet Muhammad (saw) mentioned Salat and said: For him who remains mindful of his salat, it will be a light and anargument in his favour and a means of his salvation on the Day of Judgement; and for him who is not mindful of his salat, there shall be neither a light, nor an argument in his favour, nor a means for his salvation. And on the Day of judgement, he will be with Fir´aun, Haman and Ubayy ibne Khalaf.

(Musnad Ahmad, Majma uz -Zawaid)

NOTE:

Fir´aun was the king of Egypt at the time of Musa (A:S), Haman was his minister, and Ubayy ibne Khalaf was an ardent idolater and adverdary of Prophet Muhammad (saw).
