Ramadaan

Abu Hurairah reported that the Messenger of Allaah (saws) said: "Ramadaan has come to you - a blessed month. Allaah has made it obligatory on you to fast in it. During this month, the gates of heaven are open, the gates of the Hellfire are closed and the evil devils are chained. To Allaah belongs a night in it, which is better than a thousand months. Whosoever is prevented from its good, then he has been deprived."

The Perfection of Tawheed

Shaykh ul Islaam Ibn Taymiyah (Rahimahullaah) said:
“The perfection of Tawheed is found when there remains nothing in the heart except Allah, the servant is left loving those He loves and what He loves, hating those He hates and what He hates, showing allegiance to those He has allegiance to, showing enmity to those He shows enmity towards, ordering what He ordered and prohibiting what He prohibits.”
