al-Ism al-A'zam

Al-Ism al-Aʿẓam (Arabic: الاسم الأعظم), literally "the Greatest Name",[1][2][3][4] also known as Ism Allah al-Akbar (اسم الله الأکبر, 'the Greatest Name of God'),[5][6] refers in Islam to the greatest name of Allah,[7][8] known only to the prophets.

According to some Islamic hadiths, whoever calls to God using al-Ism al-A'zam, his or her prayer (du'a) will be granted.

[9][10][11] In Shi'a Islam, al-Ism al-A'zam is believed to have a powerful effect in the act of blessing.
