Hashim Amir-Ali, The Message of the Qur’an: Presented in Perspective (1974)

119 O ye who have believed! Mind ye always Allah and side ye always with the Truthful.

120 Behoved it not the people of Madina, and the desert Arabs in its environs, to forsake the Prophet of Allah — nor to prefer their own lives to his : because, experience they no hunger, no thirst, no ordeal in the cause of Allah; nor do they step a step against the ire of the infidels; no suffering they suffer at the hands of enemies but that it is recorded to their credit, as a righteous act. Verily, Allah overlooketh no deed performed by the righteous.

121 And no contribution do they contribute, however small or big; no valley do they cross but that it is recorded so that Allah may reward them in excess of what they had performed.

122 Behoveth not the Faithful that they should march forth all at once. Why should not one from every section hold back and form a group to aquire understanding in matters of religion, so that it may instruct its people when they’re back and they may thus be trained in conscientiousness?
