Alhamdulillah (Arabic: ٱلْحَمْدُ لِلَّٰهِ, al-Ḥamdu lillāh) is an Arabic phrase meaning "praise be to God",[1] sometimes translated as "thank God" or "thanks be to the Lord".
[3] A longer variant of the phrase is al-ḥamdu l-illāhi rabbi l-ʿālamīn (ٱلْحَمْدُ لِلَّٰهِ رَبِّ ٱلْعَالَمِينَ), meaning "all praise is due to God, Lord of all the worlds", the first verse of Surah Al-Fatiha, the opening chapter of the Quran.
The phrase is frequently used by Muslims of every background due to its centrality in the texts of the Quran and Hadith, the words of the Islamic prophet Muhammad.
So frequently do Muslims and Arabic-speaking Jews and Christians invoke this phrase that the quadriliteral verb hamdala (Arabic: حَمْدَلَ), "to say al-ḥamdu li-llāh" was coined, and the derived noun ḥamdala is used as a name for this phrase.
The triconsonantal root Ḥ-M-D (Arabic: ح م د), meaning "praise", can also be found in the names Muhammad, Mahmud, Hamid and Ahmad, among others.
