In verse 126: يُفْتَنُونَ فِي كُلِّ عَامٍ مَّرَّةً أَوْ مَرَّتَيْنِ (they are put to trial every year once or twice), hypocrites have been warned about their incorrigible hypocrisy and constant breach of trust which brought all sorts of troubles for them every year once or twice. They saw the defeat of their disbelieving accomplices, the kuffar of Makkah. Then, they had to face the disgrace brought upon them when their hypocrisy was exposed. So, there was no dearth of warning signals for them. Incidentally, the count of ` once' or ` twice' here does not signify the numbers one and two as such. In fact, the purpose is to stress that this chain of action and reaction keeps moving all the time yet they take no lesson from what happens to them.
Allah says, do not these hypocrites see,
(that they are put in trial), being tested,
(once or twice every year Yet, they turn not in repentance, nor do they learn a lesson.) They neither repent from their previous sins nor learn a lesson for the future. Mujahid said that hypocrites are tested with drought and hunger. Allah said;
(And whenever there comes down a Surah, they look at one another (saying): "Does any one see you" Then they turn away. Allah has turned their hearts because they are a people that understand not.) This describes the hypocrites that when a Surah is revealed to the Messenger of Allah ,
(they look at one another), they turn their heads, right and left, saying,
("Does any one see you" Then they turn away. ..) turning away from, and shunning the truth. This is the description of hypocrites in this life, for they do not remain where the truth is being declared, neither accepting nor understanding it, just as Allah said in other Ayat,
(Then what is wrong with them that they turn away from admonition As if they were wild donkeys. Fleeing from a lion.)74:49-51, and,
(So what is the matter with those who disbelieve that they hasten to hear from you. (Sitting) in groups on the right and on the left.)70:36-37. This Ayah also means, what is the matter with these people who turn away from you to the right and to the left, to escape from truth and revert to falsehood Allah's statement,
(Then they turn away. Allah has turned their hearts (from Truth)) is similar to,
(So when they turned away, Allah turned their hearts away.) 61:5. Allah said next,
(because they are a people that understand not. ) They neither understand Allah's Word nor attempt to comprehend it nor want it. Rather, they are too busy, turning away from it. This is why they ended up in this condition.
