Abbas - Tanwîr al-Miqbâs min Tafsîr Ibn ‘Abbâs
(And on the day when those who disbelieve) in Muhammad (pbuh) and the Qur'an (are exposed to the Fire) before they eventually enter it, ((they will be asked): Is not this) chastisement (real) just? (They will say: Yea, by our Lord) it is just. (He will say: Then taste the doom for that you disbelieved) in Muhammad (pbuh) and the Qur'an.
And on the day when those who disbelieve are exposed to the Fire, when they are being chastised in it, it will be said to them: ‘Is not this, chastisement, the truth?’ They will say, ‘Yes, by our Lord!’ He will say, ‘Then taste the chastisement for what you used to disbelieve [in]’.
(Therefore be patient as did those of determination among the Messengers.) meaning, as they were patient with their people's rejection of them. "Those of determination'' among the Messengers are Nuh, Ibrahim, Musa, `Isa and the last of all of the Prophets, Muhammad. Allah has specifically mentioned their names in two Ayat: Surat Al-Ahzab (33:7) and Surat Ash-Shura (42:13).
وَلاَ تَسْتَعْجِل لَّهُمْ
(and be in no hurry for them.) which means, `do not rush the punishment for them.' This is similar to Allah's saying:
(And on the Day when He shall gather them together, (it will be) as if they had not stayed but an hour of a day. They will recognize each other.)(10:45) Then Allah says,
(A clear message.) meaning, this Qur'an provides a clear concept.
فَهَلْ يُهْلَكُ إِلاَّ الْقَوْمُ الْفَـسِقُونَ
(But will any be destroyed except the defiantly rebellious people) Which means that Allah does not destroy anyone except those who choose the way of destruction. It is part of Allah's justice that He does not punish anyone except those who deserve the punishment -- and Allah knows best. This concludes the explanation of Surat Al-Ahqaf. And all praise and blessings are due to Allah. Both success and protection from faults are by His help.
