Sūrah No. 12, Revealed in Makkah, 111 verses.
The story of Nabī Yūsuf A is the only story in the Quran which is narrated entirely in one Sūrah. The whole Sūrah is about the story except its last few verses. The Sūrah conveys God’s care for His sincere servants by giving them strength and success in very difficult conditions.
According to Tafsīr-e Namūneh the ahādīth that say Sūrat Yūsuf should not be taught to women, perhaps because of the story of Prophet Yūsuf (a) and the wife of the Minister, do not have a reliable chain of narrators. On the contrary there are Hadīth that emphasize teaching this Sūrah to families as it has many lessons for family relationships, including on preserving chastity in the face of temptation.
