“I once said to Abu Ja‘far (a.s.), ‘I pray to Allah to keep my soul in service for your cause, we perform Salah (prayer) with these people on Friday and they perform in a certain time. What must we do? He (the Imam) said, ‘Perform Salah (prayer) with them? Humran then went to Zurarah and said to him, ‘We are commanded to perform Salah (prayer) with them with their Salah (prayer)? Zurarah said, ‘This cannot be accepted without interpretation? Humran said to him, ‘Come and hear it from him (the Imam)? He (the narrator) has said that both went to him (the Imam) and Zurarah said, ‘I pray to Allah to keep my soul in service for your cause, Humran thinks you have commanded us to perform Salah (prayer) with them and I did not accept it? He (the Imam) said to us, ‘Ali ibn al- Husayn (a.s.), would say two Rak‘at with them and when they would complete he stand up to perform two more Rak‘at?” (Ahadith 1-7 are best explained by fatwa.)
