Strive hard towards achieving goals with dedication & faithfulness; Work sincerely & faithfully; Fight for Allah's cause; Receive great rewards from God if done sincerely & faithfully .

This hadith speaks about the rewards that a Mujahid, or fighter in the path of Allah, will receive. It is narrated on the authority of Alqama b. Murthad who said that it will be said to a Mujahid to take from his noble deeds whatever he likes. The Prophet Muhammad then asked what do you think he will leave anything? Meaning that all his good deeds would be taken away as reward for his efforts in fighting for Allah's cause. This hadith teaches us that those who strive and fight in Allah's cause are rewarded greatly and their efforts are not forgotten by Him. It also encourages us to strive hard and work towards achieving our goals with dedication, as we can expect great rewards from God if we do so with sincerity and faithfulness.
