Strive in the cause of God, Do good deeds

This hadith speaks to the importance of striving in Allah’s cause. It encourages believers to fight for what is right and just, as those who do so will be rewarded by meeting Allah without any deficiency or mark on them. This means that they will have no regrets or sins that they need to answer for when they meet Him. It also implies that those who do not strive in His cause may have deficiencies or marks on them when they meet Him, which could lead to punishment or regret. Therefore, this hadith serves as a reminder for believers to strive in His cause and do good deeds so that they can meet Him with no deficiency or mark on them.
