560. Commandment – Slacken not, nor grieve; and you shall certainly have the upper hand, if you are believers

[3:140] Slacken not, nor grieve; and you shall certainly have the upper hand, if you are believers. [3:147] And many a Prophet there has been beside whom fought numerous companies of their followers. They slackened not for aught that befell them in the way of Allah, nor did they weaken, nor did they humiliate themselves before the enemy. And Allah loves the steadfast.

[4:105] And slacken not in seeking these people. If you suffer, they too suffer even as you suffer. But you hope from Allah what they hope not. And Allah is All-Knowing, Wise.
