Assalamo Alaikum,
Fwd’ing
The disease of the heart occurs due to two basic matters:
The corruption of knowledge
The corruption of intent.
These in turn lead to two fatal illnesses: misguidance and anger, misguidance being the end result of the corruption of knowledge and anger being the end result of the corruption of intent. These two illnesses are the lords of all the diseases of the heart.
When one asks for guidance to the Straight Path then he is asking for that which will cure the disease of misguidance. This is why this Surah (al-Faatihah) has been made obligatory upon every servant in every prayer.
Actualising the verse, “You Alone we worship and You Alone we ask for help” serves as a cure for the corruption of intent. This is because the intent is linked to the objectives and means of attaining them. Therefore this cure is composed of six matters:
Worshipping Allaah Alone
By performing what He commanded and legislated
Not by following ones own desires
Neither by following the mere opinions of people
By asking Allaah for His Help to enact this
And not relying on oneself
Furthermore the heart is beset with two dangerous and destructive diseases and this verse serves as a cure for them. Ibn Taymiyyah said,
‘You Alone we worship’ represses ostentation and ‘You Alone we ask for help’ represses arrogance.
As regards its curing the bodily illnesses then this can be seen in the hadeeth of Abu Sa`eed (ra) reported in Saheeh Bukhaaree that after he had recited it to cure a person who had been bitten by a scorpion, the Messenger of Allaah (SAW) said to him,
And what made you to know that it was a ruqya (the Spiritual Cure)? [This discussion is summarised from ibn al-Qayyim, ‘Madaarij as-Saalikeen’ [1/64-66]]
