Hadith 134
Hazrat Shurayh narrates that I asked Sayyidah Aisha (may Allah be pleased with her), "When the Noble Prophet (peace be upon him) would enter the house, what would he begin with?" She replied, "With the miswak." In Yusuf's narration, the words are « اِذَا دَخَلَ بَيْتَهُ » "When you would enter your house."
