Don't be Sad
Hold a good opinion of your Lord
William James said:
"God forgives us our sins, but our nervous systems do not."
Ibn al-Wazeer wrote in his book Al-Awuosim wa al-Qowdosimr
"Verily, to be hopeful of Allah’s mercy opens the doors of optimism for one of His slaves, making him more avid in worship, and inspiring him to be more enthusiastic in performing voluntary acts of worship and racing to perform good deeds."
This is true, especially because some people are not moved to do good deeds except when they recall Allah’s mercy, forgiveness, and generosity. As a consequence of reflecting on these qualities, they seek closeness to Allah through diligently performing good deeds.
