Strive for sincerity in worship and actions

On the Day of Judgement, all believers in Allah will prostrate themselves before Him in reverence and awe. However, there are some people who may have pretended to be pious and religious during their lifetime by performing acts such as prostration for show or reputation. These people will try to prostrate on that day but their backs will be stiff like a single vertebrae due to their lack of sincerity. This hadith teaches us that we should always strive for sincerity in our worship and actions so that we can receive true reward from Allah on the Day of Judgement.
