‘Ā’ishah reported that Jibrīl brought her image in a piece of green silk to the Prophet (may Allah's peace and blessings be upon him) and said: "This is your wife in the world and the Hereafter."
Jibrīl brought ‘Ā’ishah (may Allah be pleased with her) wrapped in green silk to the Prophet (may Allah's peace and blessings be upon him) while he was sleeping. The meaning is that he was dreaming, and this did not take place in reality. And he said to the Prophet (may Allah's peace and blessings be upon him): "This is the woman who is to be your wife in this world and the Hereafter."
