عَنْ أَبِي بَلْجٍ عَنْ عَمْرِو بْنِ مَيْمُونٍ قَالَ قَالَ أَبُو هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ لِي نَبِيُّ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَا أَبَا هُرَيْرَةَ هَلْ أَدُلُّكَ عَلَى كَلِمَةٍ كَنْزٍ مِنْ كَنْزِ الْجَنَّةِ تَحْتَ الْعَرْشِ قَالَ قُلْتُ نَعَمْ فِدَاكَ أَبِي وَأُمِّي قَالَ أَنْ تَقُولَ لَا قُوَّةَ إِلَّا بِاللَّهِ قَالَ أَبُو بَلْجٍ وَأَحْسَبُ أَنَّهُ قَالَ فَإِنَّ اللَّهَ عَزَّ وَجَلَّ يَقُولُ أَسْلَمَ عَبْدِي وَاسْتَسْلَمَ قَالَ فَقُلْتُ لِعَمْرٍو قَالَ أَبُو بَلْجٍ قَالَ عَمْرٌو قُلْتُ لِأَبِي هُرَيْرَةَ لَا حَوْلَ وَلَا قُوَّةَ إِلَّا بِاللَّهِ فَقَالَ لَا إِنَّهَا فِي سُورَةِ الْكَهْفِ وَلَوْلَا إِذْ دَخَلْتَ جَنَّتَكَ قُلْتَ مَا شَاءَ اللَّهُ لَا قُوَّةَ إِلَّا بِاللَّهِ
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him), he says: The Prophet of Allah said to me: O Abu Hurairah! Shall I guide you to such a phrase which is one of the treasures of Paradise beneath the Throne? I said: Yes, may my parents be sacrificed for you. You (peace and blessings be upon him) said: Your saying, "Lā quwwata illā billāh" (There is no power except with Allah). Abu Balj, the narrator, says: I think that you (peace and blessings be upon him) said: Allah Almighty says in response: My servant has become obedient and submissive. I said to Amr: Abu Balj says that Amr said: I said to Sayyiduna Abu Hurairah (may Allah be pleased with him): "Lā ḥawla wa lā quwwata illā billāh"? He said: No, this phrase is in Surah Al-Kahf, as the statement of Allah Almighty is: {وَلَوْلَا إِذْ دَخَلْتَ جَنَّتَکَ قُلْتَ مَا شَائَ اللّٰہُ لَا قُوَّۃَ إِلَّا بِاللّٰہِ} … And when you entered your garden, why did you not say, "What Allah has willed; there is no power except with Allah"? (Surah Al-Kahf: 39)
