Therefore if they repent...
Therefore if they repent, it will be better for them; and if they turn away, Allah will chastise them with a painful chastisement in this world and the Hereafter, and they shall not have on the earth any guardian or any helper.”*** This holy verse includes all the plots that the hypocrites designed and acted against the Holy Prophet (S) and Islam, but most of the commentary books compiled by the Shi‘ite and the Sunnite commentators have concerned it to the plot which is known as the ‘Laylatul-‘Aqabah’ (the Night of ‘Aqabah) where the hypocrites waited in ambush in a neck of land in order to cause the murder of the Prophet (S) by startling his camel.
But their plot was found out and they failed. The verse says: “They swear by Allah that they have said nothing, but they certainly have said the word of infidelity and disbelieved after their Islam, and they determined upon what they never attained to…” It has been cited that when the Prophet (S) was speaking for the audience in Tabūk, a hypocrite, by the name of Hallās, uttered a blasphemous ugly word. One of the Prophet’s companions (‘Āmir-ibn-Qays) informed that insolence to the Prophet (S).
He summoned Hallās, but he denied the matter. ‘Āmir said that he told a lie and repeated that word. Then, by the command of the Prophet (S) both of them went near the pulpit of the mosque and swore. ‘Āmir asked Allah to send down a verse and to disgrace the hypocrite publicly.
This holy verse was revealed containing the phrase saying: “They swear by Allah that they have said nothing, but they certainly have said the word of infidelity and disbelieved after their Islam, and they determined upon what they never attained to…” Then, at the end of the verse, the Qur’ān denotes that if the hypocrites repent and really embrace Islam it is better for them, viz, Allah will forgive them.
But if they turn away and remain in their hypocrisy, they must know that Allah will punish them severely both in this world and the coming world, and they will not have any friend or helper on the earth. The verse continues saying: “…and they did not find fault except because Allah and His Messenger enriched them out of His grace.
