When the Prophet (pbuh) mentioned to them all those blessings, they agreed that all those blessings came from Allah, but then they denied this afterward, and said: no, we have all these blessings through the intercession of our gods. Allah said in response: (They know the favour of Allah) they acknowledge that all these blessings are from Allah (and then deny it) saying: we got them through the intercession of our gods. (Most of them are ingrates) all of them are disbelievers in Allah.
