عَنْ عَمْرِو بْنِ شُعَيْبٍ عَنْ أَبِيهِ عَنْ جَدِّهِ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((مَنْ مَسَّ ذَكَرَهُ فَلْيَتَوَضَّأْ، وَأَيُّمَا امْرَأَةٍ مَسَّتْ فَرْجَهَا فَلْتَتَوَضَّأْ))
It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever touches his private part should perform ablution, and likewise, any woman who touches her private part should also perform ablution.
