Jami` at-Tirmidhi, Volume 6, Book 46, Hadith 3581 (DarusSalam) ⓘ
Qais bin Sa`d bin `Ubadah narrated, : that his father offered him to the Prophet to serve him. He said: “So the Prophet passed by me, and I had just performed Salat, so he poked me with his foot and said: ‘Should I not direct you to a gate from the gates of Paradise?’ I said: ‘Of course.’ He said: ‘There is no might or power except with Allah (Lā ḥawla wa lā quwwata illā billāh).’”
حَدَّثَنَا أَبُو مُوسَى، مُحَمَّدُ بْنُ الْمُثَنَّى حَدَّثَنَا وَهْبُ بْنُ جَرِيرٍ، حَدَّثَنَا أَبِي قَالَ، سَمِعْتُ مَنْصُورَ بْنَ زَاذَانَ، يُحَدِّثُ عَنْ مَيْمُونِ بْنِ أَبِي شَبِيبٍ، عَنْ قَيْسِ بْنِ سَعْدِ بْنِ عُبَادَةَ، أَنَّ أَبَاهُ، دَفَعَهُ إِلَى النَّبِيِّ صلى الله عليه وسلم يَخْدُمُهُ . قَالَ فَمَرَّ بِيَ النَّبِيُّ صلى الله عليه وسلم وَقَدْ صَلَّيْتُ فَضَرَبَنِي بِرِجْلِهِ وَقَالَ " أَلاَ أَدُلُّكَ عَلَى بَابٍ مِنْ أَبْوَابِ الْجَنَّةِ " . قُلْتُ بَلَى . قَالَ " لاَ حَوْلَ وَلاَ قُوَّةَ إِلاَّ بِاللَّهِ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ مِنْ هَذَا الْوَجْهِ .
