`Ali bin Abi Talhah reported that Ibn `Abbas commented on the Ayah:
[يحَسْرَةً عَلَى
الْعِبَادِ]
(Alas for mankind!), this means, woe to mankind! Qatadah said:
[يحَسْرَةً عَلَى
الْعِبَادِ]
(Alas for mankind!) means, "Alas for mankind, who have neglected the command
of Allah.'' The meaning is that they will feel regret and sorrow on the Day of
Resurrection. When they see the punishment with their own eyes; they will regret
how they disbelieved the Messengers of Allah and went against the commands of
Allah, for they used to disbelieve in them in this world.
[مَا يَأْتِيهِمْ
مِّن رَّسُولٍ إِلاَّ كَانُواْ بِهِ يَسْتَهْزِءُونَ]
(There never came a Messenger to them but they used to mock at him.) means,
they disbelieved him and made fun of him, and rejected the message of truth with
which he had been sent.
