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 (a.s.), say, ‘Ali ibn al-Husayn (a.s.), while bowing down for Sajdah (prostration) would say Takbir (Allah is great beyond description).”’ (Ahadith 4-5 are best be explained by fatwa.)
