Hadith 13:17
Ahmad and al-Arba'a have:
He said, "Verily! Allah, the Most High, will not do anything with the affliction your sister imposes on herself. Command her to cover her head and to ride, and to fast three days."
وَلِلْخَمْسَةِ فَقَالَ: { " إِنَّ اَللَّهَ لَا يَصْنَعُ بِشَقَاءِ أُخْتِكَ شَيْئاً, مُرْهَا: [ فَلْتَخْتَمِرْ ], وَلْتَرْكَبْ, وَلْتَصُمْ ثَلَاثَةَ أَيَّامٍ" }
