(8) باب الْقَوْلِ الَّذِي يُفْتَتَحُ بِهِ الصَّلاَةُ
It was narrated from Abdullah bin Umar that:
A man stood behind the Prophet of Allah (ﷺ) and said: "Allahu Akbaru kabira wal-hamdu Lillahi kathira, wa subhan-Allahi bukratan was asila (Allah is Most Great and much praise be to Allah and glorified be Allah at the beginning and end of the day)." The Prophet of Allah (ﷺ) said: "Who spoke these words?" A man said: "I did, O Prophet of Allah (SWT)." He said: "Twelve angels rushed (to take them up)."
