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.‏ [1]‏ فَقَالَ: {

إِنَّ اَللَّهَ لَا يَصْنَعُ بِشَقَاءِ أُخْتِكَ شَيْئاً, مُرْهَا: [ فَلْتَخْتَمِرْ ], وَلْتَرْكَبْ, وَلْتَصُمْ ثَلَاثَةَ أَيَّامٍ

} [2]‏ .‏
