Sunan Abi Dawud, Hadith 1287 ⓘ
Narrated 'Abd Allah b. Shaqiq: I asked 'Aishah: Did the Messenger of Allah pray in the Duha? She replied: No, except when he returned from his journey. I then asked: Did the Messenger of Allah recite the surahs combining each other? She said: He would do so in the mufassal surahs.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، حَدَّثَنَا الْجُرَيْرِيُّ، عَنْ عَبْدِ اللَّهِ بْنِ شَقِيقٍ، قَالَ سَأَلْتُ عَائِشَةَ هَلْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي الضُّحَى فَقَالَتْ لاَ إِلاَّ أَنْ يَجِيءَ مِنْ مَغِيبِهِ . قُلْتُ هَلْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَقْرِنُ بَيْنَ السُّورَتَيْنِ قَالَتْ مِنَ الْمُفَصَّلِ .
