SHAFAQNA – It is narrated from Imam Ali (AS) who said: If you only deal with small and less important tasks, you will be hindered from important and vital tasks; as dealing with important tasks can lead to forgetting the small tasks, and then they (small tasks) will become difficult and important tasks. Therefore, as you prioritise important tasks, do not neglect small tasks, and leave small tasks to someone you consider as a competent person . In another narration, Imam Ali (AS) said: If recommended prayers (Mostahabat) harms your obligatory ones (Wajibat), leave Mostahab . Imam Ali (AS) also said: Any person, who pays attention to unimportant task, will lose things which are more important .
