And when he mentioned what is for the ignorant as a warning and a caution, he mentioned what is for their opposites as a promise and a glad tidings. So he said, responding to those who long for that, confirming the denial of those who deny it: "Indeed, those who have believed" meaning: in what Allah has given them of beneficial knowledge, "and have done righteous deeds" such as zakat and others, so that their deeds may be lawful and beneficial. And when the opening of the Surah with 'the Most Gracious, the Most Merciful' indicates that the apparent causes have vanished in the presence of the true cause, which is His mercy, he omitted the conjunction, saying to indicate the greatness of the reward, because its cause is the mercy of the Most Merciful. If it had been with the conjunction, it would have indicated that it is according to the measure of the deed which is its cause: "For them is a great reward" meaning: immense, "uninterrupted" meaning: not cut off - as a reward for their generosity with the little of their wealth in zakat and others, and what Allah has commanded of their words and actions in the Hereafter and this world. And 'uninterrupted' means 'cut off'; when I cut the rope, I cut it by cutting its benefits. And from it is their saying: 'The travel has cut him off' meaning: it has severed him and taken away his benefits.
