Life is a matter of just a few days. Muster up some courage and do not fulfil your urge to sin. Make the urge of sin dry up in the rays of the sun of mujahadah (striving) just like how the sun in the sky dries up dung. If you do not fulfill the urge to sin, the light of taqwa will be created. But if a person does not allow the dung to dry up and lets the cattle continue defecating fresh dung, then whatever was dried up by the sun will also become soft and will not be allowed to become dry. The earth which had become hot will now become cold. The bounty of the sun’s rays will be destroyed.
In the same way some people waste the efforts of their Sheikh by not being cautious.
To Allah do I present my complaint.
