La ilaha illallah لَا إِلَٰهَ إِلَّا ٱللَّٰهُ - Zikr-e-qualbi {Daily Zikr}

When we say “La Illaha Illa Allah”, we are affirming that there is no god but Allah (ta’ala). Every Muslim believes in this and testifies to it.
Saying La illaha illa Allah affirms your faith, yes. But did you know that saying it also has benefits that bring you reward in the sight of Allah (ta’ala)? Here are three benefits to motivate you to keep your tongue moist with La illaha illa Allah.
Forgiveness of Sins: It was narrated from Mu’adh bin Jabal that the Messenger of Allah(ﷺ) said: “There is no soul that died bearing witness to La ilaha illallah, and that I am the Messenger of Allah, from the heart with certainty, but Allah will forgive it.” (Ibn Majah)
Acceptance of Dua: Narrated ‘Ubada bin As-Samit: The Prophet (ﷺ) “Whoever gets up at night and says: - ‘La ilaha il-lallah Wahdahu la Sharika lahu Lahu-lmulk, waLahu-l-hamd wahuwa ‘ala kullishai’in Qadir. Al hamdu lil-lahi wa subhanal-lahi wa la-ilaha il-lal-lah wa-l-lahu akbar wa la hawla Wala Quwata il-la-bil-lah.’ (None has the right to be worshipped but Allah. He is the Only One and has no partners . For Him is the Kingdom and all the praises are due for Him. He is Omnipotent. All the praises are for Allah. All the glories are for Allah. And none has the right to be worshipped but Allah, And Allah is Great And there is neither Might nor Power Except with Allah). And then says: - Allahumma, Ighfir li (O Allah! Forgive me). Or invokes (Allah), he will be responded to and if he performs ablution (and prays), his prayer will be accepted.” (Bukhari)
Freedom from Hell: Narrated `Utban bin Malik Al-Ansari: who was one of the men of the tribe of Bani Salim: Allah’s Messenger (ﷺ) came to me and said, “If anybody comes on the Day of Resurrection who has said: La ilaha illal-lah, sincerely, with the intention to win Allah’s Pleasure, Allah will make the Hell-Fire forbidden for him.” (Bukhari)
