1. Abi (rah) from Sa’d b. Abdillah from Ahmad b. Muhammad from al-Hassan b. Mahbub from Sa’d b. Abi Khalaf from Abi al-Hassan Musa  who said: “If an obligatory prayer is offered in prime time fulfilling all the conditions a sweet smell would come out from it just like the sweet smell that comes out when a branch of tree is broken. Hence it is obligatory on you to offer Salaat at its prime time.”
