The Messenger Of ALLAH (Sal Allahu Alaihi Wa Sallam) Said:
An Angel Residing In Baitul Muqaddas Proclaims Every Night,
Saraf And Adal Will Not Be Accepted From A Person Who Eats
Unlawful Food.
(Ihya Ulum Id-Din By Imam Ghazali)
Saraf Means Optional And Sunnat Actions And Adal Means
Compulsory Duties. In Other Words, Compulsory Duties And
Optional Duties Will Not Be Accepted From Him.
A Man Who Is Polluted With The Filth Of Unlawful And Doubtful
Things (Ill-Gotten Income) Cannot Serve ALLAH (Subhana Wa
Ta’ala) Or Gain Pleasure From His Remembrance. He Is Not
Enabled To Indulge In Such Righteous Acts. If He Ever Happens
To Do Some Good Deed, It Is Not Accepted By ALLAH But Is
Thrust Back On That Person’s Face.
Manar Dari Has Said, Obedient Devotion Is A Priceless Treasure-
Home. Its Key Is Duaa. The Teeth Of The Keys Are Lawfully
Earned Sustenance. How Can The Lock Of The Door Be Opened
With A Key Which Has No Teeth ? None Can Get Access To The
Treasure Unless The Door Is Opened. (So Obedient Devotion Is
Also Not Possible Without Lawful Sustenance.)
