Muwatta Malik #466
The Qibla
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، زَوْجِ النَّبِيِّ صلى
Yahya related to me from Malik from Hisham ibn Urwa from his
father from A'isha, the wife of the Prophet, mayAllah bless him and
grant him peace, that the Prophet, may Allah bless him and grant him
peace, saw spittle, or mucus or phlegm, on the wall of the qibla and
scraped it off.
