Tirmidhi Book 48, Hadith 3504

حَدَّثَنَا عَلِيُّ بْنُ خَشْرَمٍ، أَخْبَرَنَا الْفَضْلُ بْنُ مُوسَى، عَنْ الْحُسَيْنِ بْنِ وَاقِدٍ، عَنْ أَبِي إِسْحَاق، عَنْ الْحَارِثِ، عَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ، ‏‏‏‏‏‏قَالَ:‏‏‏‏ قَالَ لِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ:‏‏‏‏ أَلَا أُعَلِّمُكَ كَلِمَاتٍ إِذَا قُلْتَهُنَّ غَفَرَ اللَّهُ لَكَ وَإِنْ كُنْتَ مَغْفُورًا لَكَ ؟ قَالَ:‏‏‏‏ قُلْ لَا إِلَهَ إِلَّا اللَّهُ الْعَلِيُّ الْعَظِيمُ، ‏‏‏‏‏‏لَا إِلَهَ إِلَّا اللَّهُ الْحَلِيمُ الْكَرِيمُ، ‏‏‏‏‏‏لَا إِلَهَ إِلَّا اللَّهُ سُبْحَانَ اللَّهِ رَبِّ الْعَرْشِ الْعَظِيمِ .

Ali [may Allah be pleased with him] said: “The Messenger of Allah (ﷺ) said to me: ‘Should I not teach you some words that if you say them, Allah will forgive you, even if you were already forgiven?’ He said: ‘Say: None has the right to be worshipped by Allah, the Most High, the Magnificent. None has the right to be worshipped by Allah, the Forbearing, the Generous. None has the right to be worshipped but Allah. Glory to Allah, the Lord of the Magnificent Throne. (Lā ilāha illallāhul-`aliyul-`aẓīm, lā ilāha illallāhul-ḥalīmul-karīm, lā ilāha illallāh, subḥān Allāhi rabbil-`arshil-`aẓīm.)’”
