Whoever resorts to the Magnificent Lord is safe..
It is authentically reported that whenever the Prophet (may Allah’s peace and blessings be upon him) entered the mosque, he would say:“A‘ūdhu billāhi Al-‘Azhīm wa biwajhihi al-karīm wa sultānihi al-qadīm min ash-shaytān ar-rajīm (I seek refuge with Allah, the Magnificent, and with His honorable face, and His eternal domain from the accursed devil).
” He said: “If he says so, the devil will say: ‘He is granted protection against me for the rest of the day.’”
[Narrated by Abu Dāwūd; Sahīh (authentic)]
He who extols Allah by his tongue, i.e. engaging in Dhikr, will attain success and his scale of good deeds will be heavy on the Day of Judgment. The Prophet (may Allah’s peace and blessings be upon him) is authentically reported to have said:
“Two phrases are light for the tongue to utter, heavy in the Scale, and dear to the Most Compassionate: Subhānallāh wa bihamdih subhānallāh Al-‘Azhīm (Glory be to Allah and His is the praise, glory be to Allah, the Magnificent).”
[Narrated by Al-Bukhāri and Muslim]
Allah Almighty even commanded His servants to glorify Him using this name. He says:
{So glorify the name of your Lord, the Magnificent.}
[Surat al-Wāqi‘ah: 74]
The Prophet (may Allah’s peace and blessings be upon him) commanded his Ummah to glorify Allah in prayer by this name :
“As for bowing, proclaim therein the magnificence of the Lord, Exalted be He.”
[Narrated by Muslim]
