COMMENTARY on 12:104
A. Yusuf Ali:

Translation:
And no reward do you ask of them for this: it is no less than a message for all creatures. 1787
Commentary:

1787  The Divine Message was priceless; it was not for the Messenger's personal profit, nor did he ask of men any reward for bringing it for their benefit. It was for all creatures—literally, for all the worlds, as explained in 1:2. n. 20 (see also 34:47 and 36:21).
