(a) Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) relates that when the Prophet (peace and blessings be upon him) recited "Glorify the name of your Lord, the Most High" [Surah al-A'la: 1], he would say: 'Subhana rabbiya al-a'la' (Glory be to my Lord, the Most High).
(b) Abu Dawud (may Allah have mercy on him) says: Waki' (may Allah have mercy on him) was contradicted in this hadith; Abu Waki' (may Allah have mercy on him) and Shu'bah (may Allah have mercy on him) narrated this hadith from Abu Ishaq (may Allah have mercy on him), from Sa'id bin Jubayr (may Allah have mercy on him), from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) as mawquf.
