Key مفتاح

A key in a dream signifies provision, or help, or the opening of a door of knowledge and Quran that one receives from the unseen of God Most High, especially if he has keys with him, for then he will obtain provision, knowledge, and help in his affairs and against his enemies. Keys may also signify children, spies, messengers, servant boys, husbands for wives, or wealth. Keys may also signify attaining what one hopes for from the unseen of God Most High. Seeing keys signifies lands for people in high office and success for kings. A key is victory over the enemy, because of the words of God Most High:

وَأُخْرَىٰ تُحِبُّونَهَا ۖ نَصْرٌ مِّنَ ٱللَّهِ وَفَتْحٌ قَرِيبٌ ۗ وَبَشِّرِ ٱلْمُؤْمِنِينَ

“And [you will obtain] another [favor] that you love - victory from Allāh and an imminent conquest; and give good tidings to the believers.”
