The Imam’s saying: “Allah does not look at a crooked row”
Question

                We hear a lot our imams saying before starting the prayers: “Allah does not look to a crooked row”.  Is this a Prophetic hadeeth (narration) or just a saying?
Praise be to Allah.
    
    Undoubtedly a crooked row is an improper row, and the worshippers are 
    sinning if they do not make the row straight, because the Prophet (peace and 
    blessings of Allah be upon him) warned those who do not make the row 
    straight, and said: “O slaves of Allah, make your rows straight or Allah 
    will create division among you.” As for the hadeeth that you quoted, “Allah 
    does not look at a crooked row,” this is not saheeh (authentic). End quote.
    Shaykh Muhammad ibn ‘Uthaymeen (may Allah have mercy on him).  
And Allah knows best.
