Muwatta Malik, Book 9, Hadith 33 (USC-MSA) ⓘ
Yahya related to me from Malik from Zayd ibn Aslam from A'isha that she used to pray duha with eight rakas, and she would say, "I would never stop doing them even if my parents were to be brought back to life."
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَائِشَةَ، أَنَّهَا كَانَتْ تُصَلِّي الضُّحَى ثَمَانِيَ رَكَعَاتٍ ثُمَّ تَقُولُ لَوْ نُشِرَ لِي أَبَوَاىَ مَا تَرَكْتُهُنَّ .
