Nafl Prayers
salam 1.should salat nafila be done before the adhan or after adhan and before obligatory prayer? knowing that it's forbidden to pray nafila between asr and maghreb; then when is it recommended to pray nafila for asr and maghreb? before or after adhan? and before or after the obligatory prayer?also is it allowed to pray more than one 'asr prayer' at time to make up the missed prayers? 2.is a prayer valid when finished only a minute before or just at the time of adhan for next prayer? Jazakoum allah khayran.
