Is it true that the reward for dhikr restricted to a specific number is not achieved unless that number is precisely adhered to, such that the reward is lost by increasing or decreasing it by even one?

The specific adhkar (remembrances) that are assigned a certain number should be recited exactly as they were transmitted, without addition or subtraction. Deficiency prevents the full reward, and deliberate, consistent addition may not achieve the specific reward associated with that particular devotion. There is a scholarly difference of opinion regarding the effect of addition on the reward for dhikr. Some scholars believe that addition negates the specific reward, while others hold that the reward is obtained for the required number, and any addition thereafter does no harm. The matter may differ based on intention; if one intends compliance and then adds, there is no issue. However, if one adds without intention, they may lose the reward. The numbers mentioned in adhkar are significant, and some scholars consider exceeding the legally specified numbers to be among the disliked innovations, akin to increasing medicine dosages, which might nullify its benefit. However, accidental addition incurs no blame.
