the Messenger of Allah ﷺ said: “there is not anyone upon the earth who says: ‘None has the right to be worshipped but Allah, and Allah is the Greatest, and there is no might nor power except by Allah, (Lā ilāha illallāh, wa Allāhu akbar, wa lā ḥawla wa lā quwwata illā billāh) except that his sins shall be pardoned, even if they were like the foam of the sea.”  

رَسُولُ اللَّهِ ﷺ مَا عَلَى الأَرْضِ أَحَدٌ يَقُولُ لاَ إِلَهَ إِلاَّ اللَّهُ وَاللَّهُ أَكْبَرُ وَلاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ إِلاَّ كُفِّرَتْ عَنْهُ خَطَايَاهُ وَلَوْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ  

“We were with the Messenger of Allah ﷺ on a military expedition. When we returned, we overlooked Al-Madinah, and the people were pronouncing the Takbir, and they raised their voices with it. The Messenger of Allah ﷺ said: ‘Verily, your Lord is not deaf nor absent, [and] He is between you and between the heads of your mounts.’ Then he said: ‘O ʿAbdullah bin Qais, should I not inform you of a treasure from the treasures of Paradise: Lā ḥawla wa lā quwwata illā billāh (There is no might or power except by Allah).’”  

كُنَّا مَعَ النَّبِيِّ ﷺ فِي غَزَاةٍ فَلَمَّا قَفَلْنَا أَشْرَفْنَا عَلَى الْمَدِينَةِ فَكَبَّرَ النَّاسُ تَكْبِيرَةً وَرَفَعُوا بِهَا أَصْوَاتَهُمْ فَقَالَ رَسُولُ اللَّهِ ﷺ إِنَّ رَبَّكُمْ لَيْسَ بِأَصَمَّ وَلاَ غَائِبٍ هُوَ بَيْنَكُمْ وَبَيْنَ رُءُوسِ رِحَالِكُمْ ثُمَّ قَالَ يَا عَبْدَ اللَّهِ بْنَ قَيْسِ أَلاَ أُعَلِّمُكَ كَنْزًا مِنْ كُنُوزِ الْجَنَّةِ لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ
