9. Ahmad ibn Idris has narrated from Muhammad ibn Ahmad from Ya’qub ibn Yazid from Ibn Abi ‘Umayr from Ali ibn ‘Uqbah who has said the following
“Once abu al-Hassan (a.s.), saw me, in al-Madinah when I performed Salah (prayer). I bent down my head and stretched in my Ruku‘ (bowing down on one’s knees). He (the Imam) sent me a message that said, ‘You must not do so (when you are in Ruku‘).’” (Ahadith 2-9 are best explained in the form of fatwa.)
