أَطْعَمَهُم مِّن جُوعٍ وَآمَنَهُم مِّنْ خَوْفٍ
He provided food and granted them safety from fear. (106:4)
The wāw in wa-āmanahum coordinates two past-tense verbs sharing the same agent and object pronoun. Their syntax and meanings jointly support waṣl. A second essential benefit is added to the first.
In context, āmana-hum means “gave them security,” not merely “believed.” The two favors reinforce the basis on which the preceding command has been presented.
