Mukhtasar Muslim (Abridged) 1892 — Regarding saying “La ilaha

Narrated from Sayyiduna Abu Huraira (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) used to say: There is no true deity except Allah, He is alone, He honored His army and helped His servant, and He alone defeated the groups of disbelievers. After that, there is nothing.
