Overall meaning :
Muhammad is Allah’s Messenger, and his companions who are with him are firm and unyielding towards those who oppose their religion but full of mercy towards those who follow it. You see them bowing down and prostrating in prayer, seeking Allah’s grace—to admit them into Paradise—and His good pleasure. They bear on their faces the marks of their prostrations in prayer. Thus are they described in the Torah.
In the Gospel, they are described as a seed which puts forth its shoot and strengthens it, so that it grows stout and in the end stands firm on its stem, much to the delight of the sowers. Thus will Allah make the believers grow in number and strength, so that through them He may enrage the unbelievers. To the Prophet’s companions who believe and do good deeds Allah has promised forgiveness and a great reward.
