(124) باب مَنْ رَأَى الاِسْتِفْتَاحَ بِسُبْحَانَكَ اللَّهُمَّ وَبِحَمْدِكَ
Narrated Aisha, Ummul Mu'minin:
When the Messenger of Allah (ﷺ) began his prayer, he said: "Glory be to Thee, O Allah," and "Praise be to Thee" and "Blessed is Thy name, and Exalted is Thy greatness, sand there is no god but Allah."Abu Dawud said: This tradition is not well known from 'Abd al-Salam b. Harb. No one narrated this except Talq b. Ghannam. A group of narrators reported the description of prayer from (the narrator) Budail; they did not mention therein this supplication.
