بسم الله الرحمن الرحيم
لَا إِلٰهَ إِلَّا اللّٰہُ مُحَمَّدٌ رَّسُوْلُ اللّٰہِ
(البخاري: 25)
Laa-ilaa-ha illal-laa-hu Muḥammadur Rasoo-lullāh.
There is no god besides Allāh;
Muḥammad ﷺ is the Messenger of Allāh.
It goes without saying that this is the ‘Kalimah of Islām’. It is the core of ʾĪmān. Belief in it is what establishes a person as a muʾmin (believer) and a Muslim. It saves the believer from eternal doom in the Hell Fire.
