Here Allah reminds Quraysh how He blessed them by granting them access to His sanctuary which He has made (open) to (all) men, the dweller in it and the visitor from the country are equal there, and whoever enters it is safe, because he is in a place of great security, although the Arabs of the desert round about used to ambush and raid one another and kill one another. As Allah says:

For the protection of the Quraysh. The caravans to set forth safe in winter and in summer. So let them worship the Lord of this House. Who has fed them against hunger, and has made them safe from fear.

means, is the thanks that they give for this immense blessing to associate others with Him and worship others besides Him, idols and rivals?

Have you not seen those who have changed the blessings of Allah into disbelief, and caused their people to dwell in the house of destruction?

They disbelieved in the Prophet, servant and Messenger of Allah, when what they should have done was to worship Allah Alone and not associate anything with Him, and to believe in, honor and respect the Messenger, but they rejected him and fought him, and expelled him from their midst. So, Allah took His blessing away from them, and killed those of them whom He killed at Badr, then His Messenger and the believers gained the upper hand, and Allah enabled His Messenger to conquer Makkah, and He disgraced them and humiliated them (the disbelievers).

Then Allah says:

There is no one who will be more severely punished than one who tells lies about Allah and says that Allah revealed something to him at the time when Allah did not reveal anything to him, or says, ‘I shall reveal something like that which Allah revealed.’ And there is no one who will be more severely punished than one who denies the truth when it comes to him, for the former is a fabricator and the latter is a disbeliever. Allah says:

Then Allah says:

meaning the Messenger and his Companions and those who follow him, until the Day of Resurrection,

means, ‘We will help them to follow Our path in this world and the Hereafter.’

Ibn Abi Hatim narrated that ‘Abbas Al-Hamdani Abu Ahmad - one of the people of ‘Akka (Palestine) - said, concerning the Ayah:

“Those who act upon what they know, Allah will guide them to that which they do not know.” Ahmad bin Abu Al-Hawari said, “I told this to Abu Sulayman Ad-Darani, and he liked it and said: ‘No one who is inspired to do something good should do it until he hears a report concerning that; if he hears a report then he should go ahead and do it, and praise Allah because it was in accordance with what he himself felt.’”

{And verily, Allah is with the doers of good.} Ibn Abi Hatim recorded that Ash-Sha'bi said; “Isa bin Maryam, peace be upon him, said: ‘Righteousness means doing good to those who ill-treat you, it does not mean doing good to those who do good to you.’” And Allah knows best.

This is the end of the Tafsir of Surat Al-'Ankabut. All praise and thanks are due to Allah.
