A person who is particular to Salaah then really establishes his Deen... Whilst the person who neglects it is in reality demolishing his Deen (Baihaqi).\n\nUmar (ra) offered his Salaah even though his wounds were dripping with blood (Tabarani).\n\nThe one who abandons a Salaah deliberately and intentionally then becomes an unbeliever (Tabarani).\n\nShaytan's blasphemy was not prostrating to Adam (as), Thus what then of the one who refuses to prostrate to Almighty Allah SWT (Jaami Al Uloom Al Hikam).
