Mishkat al-Masabih 4 Prayer كتاب الصلاة 719

عَن أم هَانِئ قَالَتْ: إِنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ دَخَلَ بَيْتَهَا يَوْمَ فَتْحِ مَكَّةَ فَاغْتَسَلَ وَصَلَّى ثَمَانِيَ رَكَعَاتٍ فَلَمْ أَرَ صَلَاةً قَطُّ أَخَفَّ مِنْهَا غَيْرَ أَنَّهُ يُتِمُّ الرُّكُوعَ وَالسُّجُودَ. وَقَالَتْ فِي رِوَايَة أُخْرَى: وَذَلِكَ ضحى

Umm Hani’ said that the Prophet entered her house on the day of the Conquest of Mecca, bathed and prayed eight rak’as , adding, “I never saw a shorter prayer than it, except that he performed the bowing and the prostration completely.” In another version she said, “That was in the forenoon.” (Bukhari and Muslim.)
