Hadith
حَدَّثَنَا عُبَيْدُ بْنُ أَبِي قُرَّةَ، حَدَّثَنَا ابْنُ أَبِي الزِّنَادِ، عَنْ أَبِيهِ، عَنْ أَبَانَ بْنِ عُثْمَانَ، عَنْ أَبِيهِ، قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ قَالَ بِسْمِ اللَّهِ الَّذِي لَا يَضُرُّ مَعَ اسْمِهِ شَيْءٌ فِي الْأَرْضِ وَلَا فِي السَّمَاءِ وَهُوَ السَّمِيعُ الْعَلِيمُ لَمْ يَضُرَّهُ شَيْءٌ.
