وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: كَانَ ذَلِكَ قَدْ فَعَلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَصَرَ الصَّلَاةَ وَأَتَمَّ. رَوَاهُ فِي شرح السّنة
‘A'isha said, “God’s Messenger has done all that; he both shortened the prayer and observed it completely.” [Baghawi] transmitted it in Sharh as-sunna.
