He [Jacob] said, O my son! Do not describe your dreams to your brothers, if they plot against you. Indeed Satan is an open enemy of man. [Sura: Yusuf, verse: 5 (first episode)]
Tafsir: The previous verse describes the dreams of Prophet Yusuf (AS). He told his father Jacob (AS) about his dreams. In the above verse, the statement of Prophet Jacob (AS) has been mentioned. Jacob was the prophet of Allah. So he heard the description of the dream and realized that it was not a common dream. In future, Yusuf (AS) will become an ideal man. So he warned Yusuf (as) to not tell the dream to his brothers. Because they realize the meaning of dreams, brothers may jealous of Yusuf (as) and harm him.
From the above mentioned verse, it is not known to everyone about dreams.
Have a good dream to do
If one looks at a good dream, then three things will work – one. Praise Allah and say ‘Alhamdulillah’. Two It will tell others the good news. Three Dreams will tell a person who loves her. According to Hazrat Abu Qatadah (ra), the Prophet (peace be upon him) said, ‘When one of you dreams that he likes, then he will understand, it is from Allah. He will praise Allah for this dream and inform others about it.
And if you have a dream that he does not like, then understand it, it is from Satan. Then he will seek refuge with Allah from the loss of this dream and throw spit on the left three times. Do not tell anyone about this dream. Remember that this dream can not harm him. “(Bukhari, Hadith: 6583)
