Kalima is an Arabic word that means "word" or "phrase". In the context of Islam, the term "Six Kalimas" refers to six Islamic phrases or prayers that are often recited by Muslims. The phrases are taken in part from hadiths and are considered to be the basic beliefs of Muslims all around the world. The Six Kalimas are verses of the Quran and are recited to learn the fundamentals of Islam. The Six Kalimas are:

1. Kalimat aṭ-Ṭayyibah: "There is no deity but Allah (God), Muhammad is the messenger of Allah (God)."
2. Kalimat ash-Shahadah: "I bear witness that there is none worthy of worship except Allah, the one alone, without any partner, and I bear witness that Muhammad (P.B.U.H) is his servant and messenger."
3. Kalimat at-Tamjeed: "Glory (is for) Allah."
4. Kalimat at-Tawheed: "There is none worthy of worship except Allah."
5. Kalimat al-Istighfar: "I seek forgiveness from Allah."
6. Kalimat ar-Radd: "O Allah! I seek refuge in You from the punishment of the grave, and from the punishment of Hell-fire, and from the trials of life and death, and from the evil of the trial of the False Messiah."

Recitation of the Six Kalimas is taught in South Asian Muslim Schools, and the importance of learning them is disputed, with some regarding them as essential phrases to be memorized and others arguing that they are not present in the Quran or substantiated by Muhammad.
