Al-Adab Al-Mufrad #184

Umm Salama reported that the Prophet, may Allah bless him and grant him peace, was in his house and called for a slave of his (or hers) and she was slow in coming. The anger showed in his face. Umm Salama went to the curtain and found the slavegirl playing. He had a siwak-stick with him and said, '"Were it not that I fear retaliation on the Day of Rising with this siwak."
