Rain dream meaning in Islam

What al-Nabulsi wrote

Did you see rain in your dream? Al-Nabulsi wrote in Ta'tir al-Anam that rain, when it brings no harm, is good, provision and mercy. Whoever sees rain falling everywhere may see a matter that had died come back to life, and if they were worried or in debt, relief may come. Interpretation differs with the dreamer's state, and Allah knows best.

From the book

• «إذا لم يحصل منه ضرر فإنه خير ورزق ورحمة»“If no harm comes from it, it is good, provision and mercy”
• «مطرا عاما يحيا له أمر ميت وينال خيرا ونعمة وبركة وإن كان مغموما أو مديونا فرج عنه»“Rain falling everywhere: a dead matter comes to life for one, who gains good, grace and blessing; and if one was distressed or in debt, one is relieved”
