11. These people delude themselves that their hypocritical behaviour will profit them when in fact it will prove harmful both in this world and the Next. A hypocrite may be able to fool people for a while, but it does not last long; his hypocrisy is ultimately seen through. As for the Next Life, it is obvious that his claim to be a true believer is contradicted by his own actions and is thus quite worthless.
12. ' Disease' here refers to the disease of hypocrisy. The statement that 'Allah has intensified this disease' means that He does not punish the hypocrites immediately but allows them to indulge in their hypocrisy and exult in the success of their ruses. This feeling of success intensifies their hypocrisy.
13. They are being asked to become Muslims in the same manner as others of their community became Muslims
14. They think that those people who sincerely embraced Islam and thereby exposed themselves to all kinds of trials and persecutions, and confronted risks and dangers, were merely fools. To them it seems sheer folly to invite the hostility of the entire land merely for the sake of Truth and righteousness. In their view, wisdom consists not in bothering oneself with the distinction between truth and falsehood, but in remaining concerned only with one's own interests.
15. 'Satan' in Arabic means refractory, rebellious and headstrong, and is used for both human beings and jinn. Although this word is generally used in the Qur'an for the satans amongst the jinn, it is also used occasionally for human beings possessing satanic characteristics. The context generally explains whether the word 'satan' refers to jinn or to human beings. In this particular case the word 'satans' refers to those influential leaders of the time who were in the vanguard of opposition and hostility to Islam
16. This means that two opposite effects emerged when a true servant of God
radiated the light which made it possible to distinguish true from false and
right from wrong, and made the straight way distinct from the ways of error.
To those endowed with true perception, all truths became evident. But those
who were almost blinded by the worship of their animal desires perceived nothing.
The expression, 'Allah took away the light of their perception' should not create
the impression that these people were not responsible for their stumbling into
darkness. Only those who do not seek the Truth, who prefer error to guidance
and who are adamantly disinclined to pursue the Truth despite its luminosity,
are deprived, by God, of the light of their perception. God simply enables such
people to do what they wish.
