Do Not Have Tomorrow As Your Main Concern
Al-Hasan Al-Basree said:
“Beware of entering upon a day having tomorrow or other future days as your main concern and worry.
(If you do so), you will increase in anxiety and difficulty, and you will wish to collect during your day, what will suffice you for several days. How stupid! One ends up being preoccupied, one’s grief gets worse and one’s toil and labour becomes great.
And the slave ends up neglecting doing (good) deeds as a result of these hopes (he has in tomorrow and the future days).”
