Mishkat al-Masabih, 1319

‘A’isha used to pray eight <i>rak'as</i> in the forenoon, then say, “If my parents were brought back to life for me I would not give up praying them.” Malik transmitted it.

وَعَنْ عَائِشَةَ أَنَّهَا كَانَتْ تُصَلِّي الضُّحَى ثَمَانِي رَكَعَاتٍ ثُمَّ تَقُولُ: «لَوْ نُشِرَ لِي أَبَوَايَ مَا تركتهَا» . رَوَاهُ مَالك
