5ـ أَحْمَدُ بْنُ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنْ فَضَالَةَ بْنِ أَيُّوبَ عَنْ مُعَلًّى أَبِي عُثْمَانَ عَنْ مُعَلَّى بْنِ خُنَيْسٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ سَمِعْتُهُ يَقُولُ كَانَ عَلِيُّ بْنُ الْحُسَيْنِ (عَلَيْهِما الْسَّلام) إِذَا هَوَى سَاجِداً انْكَبَّ وَهُوَ يُكَبِّرُ.
5. Ahmad ibn Muhammad has narrated from al-Husayn ibn Sa‘id from Fadalah ibn Ayyub from Mu‘alla’ abu ‘Uthman from Mu‘alla’ ibn Khunayth who has said the following: “I once heard abu ‘Abd Allah عليه السلام, say, ‘Ali ibn al-Husayn عليه السلام, while bowing down for Sajdah (prostration) would say Takbir (Allah is great beyond description).”’ (Ahadith 4-5 are best be explained by fatwa.)
